For a list of issues that have been resolved, click here.

You may also want to review support documentation from other services that may be related to the issue you are experiencing.

Note: If you are experiencing message delivery delays and are interacting with a WiscList, review the documentation related to WiscList above.

All clients or multiple clients

The issues listed below apply to all or multiple email/calendar clients.

  • User is not receiving all messages in their Inbox.

    • There are several possible causes when mail stops arriving in a user's Inbox:
      • Junk Mail filtering (campus-level): In an effort to keep UW-Madison's email traffic clean and secure, campus email messages are scanned for spam/junk mail identifiers, and suspicious messages are sent to users' Junk Mail folders instead of their Inboxes. It is possible that a legitimate message could be identified as spam and sent to a user's Junk Mail folder. To learn more about Junk Mail filtering in UW-Madison's Office 365, including what you can do with messages sent to your Junk Mail, read Office 365 - Learn about junk email and phishing.

      • Inbox rules: Inbox rules may also route mail to a folder other than your Inbox. If a rule was configured incorrectly, proper mail flow could be interrupted. To learn how to see if you have any Inbox rules configured on your account, check out Office 365 - View Inbox Rules. To learn how to add, remove, or edit Inbox rules, read Office 365 (Outlook on the web | Outlook 2016 for Windows/MacOS) - Using Inbox Rules.

      • Conversation View: Conversation View is a Microsoft feature in Office 365 that, when turned on, messages that share the same subject appear as conversations that can be viewed expanded or collapsed. If conversation view is enabled, try disabling this feature to see if your missing messages appear. Manage conversation view within Outlook on the web.

      • Clutter: Clutter is a Microsoft feature in Office 365 that, when turned on, will learn your email reading habits (within Outlook desktop clients or Outlook Web App) and move less important email into the Clutter folder where they can be reviewed later. Most of the mail going into the folder should be bulk mail (advertisements) and messages from mailing lists. However, if the feature is enabled, you will want to periodically check the Clutter folder, as it may move legitimate mail into this folder. To learn more about Clutter, read Office 365 - Getting Started with Clutter.

      • Focused Inbox: Focused Inbox helps you focus on the emails that matter most to you. It separates your inbox into two tabs—Focused and Other. Your most important emails are on the Focused tab while the rest remain easily accessible—but out of the way—on the Other tab. You’ll be informed about email flowing to Other, and you can switch between tabs at any time to take a quick look. If Focused Inbox is enabled, try disabling this feature to see if your missing messages appear. Learn more about Focused Inbox.

      • Account has a forward: When a forward is set on an account, email messages sent to the forwarded account will be redirected to the destination account. You may configure a forward to save a copy of messages forwarded to the destination account or simply redirect the message without saving a copy. To learn more about forwarding in Office 365, read Office 365 - Set/Manage a Forward on a NetID or Service Account.

      • Account is shared or managed by someone else: There are instances when more than one person needs to interact with an Office 365 Service Account. When an account is shared and accessed by multiple people, someone with legitimate access to the account can move or delete messages from the account's Inbox without making other account users aware of their actions. Ensuring a proper workflow is established with those who access the account is the best way to avoid this problem. If you believe mail is missing from your shared Service Account, confirm with all others who access the account that they have not moved or deleted the mail before contacting the Help Desk. To learn more about shared accounts in Office 365, read Office 365 - Shared Departmental Service Accounts.

      • Account is configured in a non-Microsoft client like Android or iOS native mobile mail applications, Apple Mail/Calendar, or Thunderbird: Microsoft has confirmed a known issue that having your Office 365 account configured in a native (non-Microsoft) email client may sometimes cause mail flow to be interrupted or halted in your Outlook desktop email application or Outlook on the web. This issue may manifest itself as messages appearing in the Inbox of your non-Microsoft client, but those same messages will not appear in your Inbox in Outlook on the web. It's possible messages may not appear in your Inbox at all. You may be able to search for those messages in Outlook on the web and see that they are in your Inbox, but when opening your Inbox, you do not see the messages. To learn how to see the folder location of a message found via a search, read Office 365 - Find the folder location of a message when using the search function.

        • Microsoft's recommended solution is to remove your configured Office 365 account from any non-Microsoft client and, instead, use official Microsoft clients. If you try this solution and are still experiencing this issue, please contact the DoIT Help Desk.
    • User is not receiving some emails - sender receives undeliverable email which includes the following error: "Remote Server returned '554 5.2.0 STOREDRV.Deliver.Exception:ObjectNotFoundException.MapiExceptionNotFound; Failed to process message due to a permanent exception with message Cannot get ID from name.".

      • Microsoft has confirmed this as expected behavior if the user who is the intended recipient and has 'Clutter' enabled, but the Clutter folder is missing from the mailbox. Since the incoming message is classified as Clutter, it cannot be moved to the Clutter folder since it does not exist - so the message is bounced and the send receives an undeliverable message with the error.
      • Solution: disable and then re-enable Clutter - this action will recreate the Clutter folder.
    • Email messages from blocked senders start appearing in a user's Inbox instead of their Junk Mail folder.

      • There is a maximum limit of 1024 email addresses that may be added to a user's Blocked Senders list in Office 365. If more than 1024 addresses have been added to a user's Blocked Senders list, routing of blocked mail to the user's Junk Mail folder will no longer occur. However, even if only a few hundred email addresses have been added to a user's Blocked Senders list, routing of junk mail to the Junk Mail folder may become inconsistent. The user will need to remove blocked addresses from the list for mail from blocked senders to consistently routed to user's Junk Mail folder instead of the user's Inbox. Microsoft does not intend for the Blocked Senders list to house hundreds of addresses, and it is recommended that users keep the list as small as possible, only blocking senders they believe are likely to send again using that address. Keeping this list manageable at around 50 blocked addresses, is a good practice. To learn how to view your blocked senders list and manage other Office 365 Junk Mail settings, read Office 365 - View Junk Mail Filters. To learn more about Junk Mail, in general, read Office 365 - Learn about junk email and phishing

    • Can't find messages that have been moved to your top-level folder.

    • After the password for your NetID account is changed, Microsoft Outlook may repeatedly prompt you for your password or is unable to send/receive mail. After you enter the new password and then click to enable the Remember my credentials option, you are again prompted for your credentials.

    • User receives "un-responsive script error" when loading a calendar or the calendar data will not load.

      This issue may occur if the calendar you are loading or attempting to interact with has more than 1000 events in it. This can occur normally or in some cases there could be a corrupt event which is duplicated 100 or 1000 of times.

      • Solution: contact the help desk so that we can investigate the specific calendar.
    • Permission levels available for Office 365 vary across the different Outlook clients.

      • For example, the permissions levels in Outlook on the web are not the same as the permissions levels in Outlook 2013 or Outlook 2011, although some are titled similarly.
      • Please be sure that you are consistently setting permissions levels in a single client, and preferably the same client as those you are interacting with.
    • Unable to access service account via Outlook on the web (accessing/opening the account) or Outlook for Windows clients (automapping) after permissions have been granted.

      •  In some cases, the assigned permissions do not get set correctly, try the following work around
        • Outlook on the web

          1. Run the permission repair tool and reapply permissions
          2. Log/sign out of Outlook on the web (browser).
          3. Close your browser.
          4. Access the service account.
            • If you cannot access the service account, contact the DoIT Help Desk to further troubleshoot the issue.
            • If you can access the service account, permissions are set correctly and the service account is accessible.
        • Outlook for Windows client

          1. Run the permission repair tool and reapply permissions
          2. Log/sign out of Outlook on the web (browser) - only if you are currently logged into your account via a browser.
          3. Close your browser.
          4. Access the service account via browser.
            • If you cannot access the service account, contact the DoIT Help Desk to further troubleshoot the issue.
            • If you can access the service account, permissions are set correctly and the service account is accessible - issue now is with Outlook. Continue with troubleshooting Outlook for Windows
              1. Restart Outlook and see if the service account auto-maps. You may need to wait about 60 minutes for the account to load.
              2. If the service account does not auto-map, try any of the following

                Relink the account

                1. Unlink the account - wait an hour.
                2. Link the account - wait an hour.
                3. Confirm if the user can access the service account via Outlook on the web.
                  If you cannot access the service account, follow the steps above regarding Outlook on the web.
                  If you can access the service account, continue to the next step.
                4. Restart Outlook and see if the service account auto-maps. You may need to wait about 60 minutes for the account to load.

                Repair Outlook/Inbox profile

                1. Follow instructions to repair your profile.
                2. Restart Outlook and see if the service account auto-maps. You may need to wait about 60 minutes for the account to load.

                Create a new profile

                1. Follow instructions to create a new profile for the client you are using.
                2. Restart Outlook and see if the service account auto-maps. You may need to wait about 60 minutes for the account to load.
    • Messages are undeliverable/bounce when an unusual or special character is included in the subject.

      • The bounce message received will contain the following error listed within the text: "Character set name (UNKNOWN) is invalid or not installed.; cannot handle content of message with InternalId".
      • The only workaround is for the sender to remove any special or unusual characters, or characters in a foreign language, and only use plain text characters in the subject.
    • Deleted event reappears when calendar is refreshed.

      • Editor/Delegate deletes an event from another account using Outlook or Outlook on the web. After refreshing the calendar, the deleted event returns. In many cases, the owner of the calendar never sees the event deleted in the first place.
      • Microsoft is aware of this issue and is able to provide a fix. Call the Help Desk and open a case. A case with Microsoft will be opened.
    • Resource calendar permissions do not always appear to be applied after being set/configured.

      • Please wait 24 hours after setting/changing/configuring resource permissions before attempting to utilize those permissions.
    • Some calendaring functions have unpredictable results when using a different calendaring client than those you are scheduling with.

      • Some users report that event attendance is often incorrect, or simply fails to update, when using multiple clients. For best calendar performance, use the same calendaring client -- including version -- as those you schedule with frequently.
    • Unable to delete a calendar or email folder

      • When attempting to delete a secondary calendar/email folder, you may run into the error 'The calendar/folder can't be deleted'.
      • To remedy this issue, change the name of the calendar/email folder and then close the application/browser you are currently using. Restart the browser/application and access your account. Try again to delete the calendar/email folder. You may need to do this a few times before successfully removing the calendar.
    • Messages to lists have unfamiliar "From"

      • Messages to lists will display "Sender" ahead of "From"
      • Example: on behalf of Bucky Badger
    • When someone shares their calendar with you, using the link in the automatically generated email to add their calendar does not always work.

      Use Microsoft's troubleshooting steps to try to open the calendar. If this fails and you do have the appropriate permissions, use the instructions below as a workaround.

    • Event reminder cannot be modified by attendee.

      When you receive an invitation, and accept it, the reminder of the event will controlled/set by the value configured by the organizer when the organizer sent the invite. The attendee will not be able to modify this reminder.

      • This is functioning as designed. If you want to change this behaviour, please provide feedback to Microsoft.
    • Class schedules can include duplicate events

    • When editing a single instance of a recurring event, the edited event may not appear appropriately for invitees of that event.

      • In order to prevent this and any possible data corruption of your calendar from occurring, we recommend that if you would like to edit a single instance of a recurring event, delete that single instance from the recurrence and create a new event where the deleted instance would have taken place.
    • Unable to view/open attachment

      • Certain attachment types are blocked in Office 365. If you are unable to view or open an attachment, please review this document to verify that the file type is not blocked.
    • If a resource calendar is set to auto-accept meeting invitations, the title/subject of the event will list the name of the organizer when the resource calendar is viewed

    • Desktop versions of Outlook may display some emails in CJK characters (aka. Chinese characters, Han characters, kanji, etc.)

      • Open the problematic email in Outlook, click Actions > Other Actions > Encoding, and then change the encoding to Unicode (UTF-8).
      • Or, open the email via Outlook on the web. If the CJK characters still appear, you will need to open the email in an Outlook desktop client and change the encoding.
    • Filtering based on which alternate address in the To field does not produce the expected results.

      • The reason for this is because when the message is received and processed within Office 365, the alternate address is replaced by the primary address of the account.
      • A possible workaround for this is to create a matching header rule (It includes these words | in the message header...) instead - and enter the alternate address as the matching words.
    • When calendaring between different systems (e.g.,Gmail, Yahoo!, etc. to Office 365 and vice versa), the attendee may receive anywhere between 0 and 2 invitations.

      • Similar behavior should be expected when the attendee accepts or declines a meeting, and when the owner of the event cancels the meeting.
    • Sending an event invite to an "" address -- a WiscList with scheduling enabled -- will result in all Office 365 members receiving up to 3 notifications of the event.

      • The attendees will be able to take action on the event invitation from any of the notifications, but only one response is necessary.
    • If a Novell/GroupWise user invites an Office 365 resource calendar to an all day event, the event may appear from 7:00pm to 7:00pm the next day.

    • From March 1 - March 31, if an Office 365 user receives an event invitation from a WiscCal or other external calendar system, the event time will be one hour behind.

      • This issue occurs because of Daylight Saving Time. More information can be found here.
    • Calendar clients (in most case mobile clients) may not load/sync or load/sync very slowly.

      • This may occur if recurring event(s) do not have an end date set. To fix this issue, edit all recurrence events using Outlook on the web or Outlook desktop client and confirm/set a specific end data.
    • Email clients that are configured via IMAP will experience a variety of limitations and performance issues.

      • All clients connecting via IMAP will experience data throttling

        • Throttling causes a reduction of speed when downloading or moving a large number of messages
        • Throttling is controlled by Microsoft and cannot be removed
      • If throttling occurs when you are attempting to move mail, you may lose messages. For information on how to avoid this issue, click here.

      • Most IMAP flags are not supported in Office 365. Only the "Read/unread", "Important", and "Recent" flags are supported

      • If you have a client configured via IMAP, Outlook on the web will show drafts of messages you have already sent in message threads

      • For information on how to improve your IMAP client's performance, click here.

      Due to the issues listed above, configuring a client via IMAP is not recommended.

    • Issues involving Office 365 service accounts:

      • Service accounts hidden from the Global Address List (GAL) by default. However, it takes a few moments for this setting to be enabled, meaning that for the first five (or so) minutes after creation, the service account will be displayed in the GAL.

        • During this time, it is possible to subscribe to the account's calendar or use the Open mailbox feature in Outlook on the web.
        • Once this five-minute window has elapsed, users will no longer be able to subscribe to the calendar or use the open mailbox feature because the features to do so require searching the GAL.
        • To allow users to subscribe to the service account's calendar or use the open mailbox feature, you will need to show the account in the GAL using the Wisc Account Administration site.
      • When a service account is hidden from the GAL, the only way to subscribe to its calendar is to use the Add calendar option within the email invitation that is sent as a result of the service account sharing it's calendar.

        • The Add calendar option does not work in local Outlook clients. When users attempt to subscribe to the calendar, the button either does not respond or the Outlook client will crash.
        • Adding the service account to your address book will allow you to subscribe to it's calendar in desktop Outlook clients; however, the data for the calendar will not populate. Outlook on the web does not allow searching based on address book entries.
      • A service account cannot be deleted within ten minutes of creation

    • Suggested Meeting Add-In places event at incorrect time and/or on incorrect date.

      • Sometimes the Suggested Meeting Add-In does not schedule the event at the correct date/time, even though it did pick up the correct date/time in the email.
      • The event should be deleted and recreated manually.
    • Problem with resource calendars not automatically processing event invitations and cancellations

    • Changing your NetID password

      • When changing your NetID password, you must ensure that you update your clients and mobile devices accordingly and restart them because Office 365 has no facility to terminate active client sessions..

        • Update the password on the account linked to your desktop or mobile client. You can visit the following document for more information regarding client configuration/access Office 365 - Set up your mobile device or desktop client
        • Restart your mobile device or desktop client to put the change into effect.
    • Service account display names suddenly changes to include a "." in front of the name

      • Role accounts migrated as service accounts will display with a period in front of the name, for example: the name 'Bucky Badger' will appear as '.Bucky Badger.' To resolve this issue, a domain admin will need to change the first and last name by following the steps provided in this document Office 365 - Change your display name.
    • When sending as someone else in Outlook 2016/2011, if you save the message as a draft it, will disappear.

      • The current work around is to not change the 'From address' until you are ready to send the email.

    • Outlook on the web

      The issues listed below apply only to Outlook on the web. Issues occur in all browsers, unless otherwise specified.

      • Many text formatting options in Office 365 Groups conversations do nothing when clicked.

        • A case is open with Microsoft, who are working to remedy this issue. However no ETA has currently been provided for a fix.
      • Outlook on the web does not show full list of available rooms when inviting a resource.

      • Some browser extensions may cause issues with Outlook on the web.

        • If you are experiencing problems, try disabling all browser add-ons.
      • Outlook on the web always starts in Mail view, regardless of the selected start page setting

        • NetID accounts: You can now choose to log directly into any of the primary applications from the linked account login page. Example, If you wish to log directly into your calendar, click the Calendar selection.
        • Service accounts: Due to technical issues, you can only log into your mail application.
      • Signing into Outlook on the web will sometimes produces a redirect loop error message: "This webpage has a redirect loop"

        • In rare instances where this issue occurs, you will need to wait about 24 hours and try again.
        • In the meantime, you can configure a desktop client to connect to your account.
        • Microsoft was contacted but was unable to provide a solution or root cause of the problem since the issue disappears after some period of time.
      • Signing out of OWA will sometimes produce an error message

        • In instances where this issue occurs, you will be redirected to a page on the Microsoft site. The error displayed will read: "Sorry, but we're having trouble signing you out".
        • In order to fully sign out of Outlook on the web, you will need to close the browser. Click here for more information.
      • Moving large quantities of mail across folders is difficult in Outlook on the web

        • There is no "Select All" option that allows you to select all messages in a folder
        • Select a large number of messages using Shift + Left-Click is unreliable. You often get only one message, or they won't highlight at all.
        • Recommended workaround: Testing has shown that can select blocks of 20 messages. After you have selected the block, scroll down and use Shift + Left-Click to select the next block of 20 or so.
      • Error "An error occurred while searching. Please try again later." when performing a search within Outlook on the web.

        • Contact the Help Desk and open a case.
        • A case with Microsoft will need to be opened - they will run a backend tool to update the indexing on the mailbox.
      • Error "An internal server error occurred. The operation failed" when attempting to add/change image for a resource/shared mailbox.

        • Microsoft confirmed this as a known issue/behavior. When opening another mailbox via Outlook on the web, the account control cannot be maintained to the mailbox that was opened. It will only control the account you authenticated with.
      • Error "User was unable to access their account due to move error" when attempting to log into your account.

        • Microsoft confirmed this as a known issue/behavior and provided the following response: "Sometimes, unfortunately, this kind of outage does happen due to regular Exchange Online maintenance. When we find overloaded workloads in certain data centers, the backend team initiates move requests from one data center to another. While these are online moves and do not affect the end user experience, this error can happen because the mailbox move request was stuck in finalization phase. We have taken steps to stay on top of finalization phases hang up like this and working to increase our customer experience."
      • User is unable to open your calendar or work as the permissions you have been granted after the owner of the calendar has successfully shared it with you.

        • In some occasions, resetting the permissions using the email address of the person you are sharing with may solve the issue.
          •  Sometimes, the following workaround works:
            1. As the owner of the calendar, remove the user from the permissions listing.
            2. Wait 30-60 minutes for this change to be synced.
            3. Use the steps above to add the user again but this time add them by using their email address to look them up. Make sure to select "Use this address:..." option.
            4. Wait 30-60 minutes for this change to be synced.
            5. Ask the user to verify if they now have the assigned permissions.
      • Conversation view occasionally displays an earlier message of an email thread as the most recent message.

        • For example, if an email thread has an original message and four unique responses, Outlook on the web might replace the most recent message (Message 5) with the content of say, Message 2.
        • This bug affects only the view of the conversation thread and does not reflect actual content of emails stored on the server.
        • To resolve this issue, reload Outlook on the web. If reloading the web client is unsuccessful, clear your browser's cache and cookies.
      • Add-in action/button disabled when accessing/opening another account.

        • For example, when you are granted full mailbox permissions to another account and access that mailbox either via linked login or "open another mailbox..." feature, the Add-in button/feature will be greyed out and unavailable to you.
        • Microsoft confirmed that this behavior is functioning as designed.
      • When opening a Service account via linked login, you will occasionally be directed to the linked NetID mailbox.

      • Error "Something went wrong", "Bad Request", or "Error: you don't have permissions to send messages from this mailbox"error when attempting to open/access/send message with a service account using Open another mailbox... action, clicking on the service account via the Office 365 sign-in screen, or sending a message when changing the from address.

        • This error appears because your account does not have the proper permissions (linked) or your permissions are no longer working to access the account.
          •  Current Work Around - the domain administrator should perform the following steps to re-assign your permissions
            1. Follow these steps to access the service account within Wisc Account Administration site.
            2. Use the Permission Repair Tool to reapply these permissions.

            •  If the above does not work, try the following work around - the domain administrator should perform the following steps to re-assign your permissions

              For service account

              1. Follow these steps to access the service account within Wisc Account Administration site.
              2. Within the "Linked Accounts" page, remove the NetID having this issue. Important: if only one NetID is currently linked, you must add another NetID (add your own) before removing the NetID in question. You will remove your NetID in this last step.
              3. Wait 30-60 minutes.
              4. Within the "Linked Accounts" page, add the NetID having this issue.
              5. Wait 30-60 minutes.
              6. Have the user log out and log back into Outlook on the web again and try accessing the account.
              7. If you added your NetID temporarily, remove it.

              For resource account

              1. Follow these steps to access the service account within Wisc Account Administration site.
              2. Within the "Edit Resource" page, replace the 'Owner Email' with some other account. Important: You will replace this with the original account at the end of these steps.
              3. Wait 30-60 minutes.
              4. Within the "Edit Resource" page, replace the 'Owner Email' back to the original account having this issue.
              5. Wait 30-60 minutes.
              6. Have the user log out and log back into Outlook on the web again and try accessing the account.
      • Error "Bad Request" when attempting to open a resource mailbox using Open another mailbox... action.

        • This is working as designed.
        • The reason for the error is because you do not have full-mailbox permissions to the resource mailbox. Contact the owner of the resource so that they can grant you the necessary permissions.
      • Outlook on the web offers limited support for S/MIME digital signatures

        • You cannot create digitally signed email using Outlook on the web. You may receive the following error, "An error occurred while sending this S/MIME message. The certificate used to sign this message isn't trusted by your organization.", when you attempt to send a message that you enable to send as digitally signed. If you need to send digitally signed emails, a desktop email application, such as Outlook, is recommended.

        • In Conversation view or the Preview pane you may not be able to read, reply to, or forward digitally signed email messages depending on which version of Outlook on the web your account is on.

          Possible issues/solutions:

      Mobile Devices

      The issues listed below apply to mobile devices. If the issue only affects certain device(s), affected device(s) will be listed in the issue description.

      • Some calendar-related actions are possible to perform using a mobile device, but can cause issues.

      • Current issues with Microsoft Exchange ActiveSync and third-party devices

      • Samsung devices running an Android OS will show duplicate calendar events.

        • This is due to an issue with the way Samsung implemented its calendar application. More information can be found here.
        • One possible workaround is to subscribe in Google Calendar to your Office 365 calendar via ShareURL.
      • On the Outlook for iOS or Android application configured with Exchange ActiveSync protocol, drafts will not sync.

        • The "Drafts" folder on your Outlook for iOS or Android application will not sync with the "Drafts" folder on Microsoft's server and vice versa.
        • Drafts saved using your Outlook for iOS or Android application can only be access using the application on your device.
        • Drafts saved using Outlook on the web or a desktop client can be accessed using any client except your Outlook for iOS or Android application on your device.
      • The OWA app for Android and iOS does not work with UW-Madison's implementation of Office 365

        • The OWA app for Android and iOS is not compatible with the type of authentication (Shibbotleth) used by UW-Madison.
        • Instead of using this app, Android and iOS users should configure their device's native email/calendar client. Instructions are available here.
      • When you add an Exchange account using ActiveSync on an Android phone, some phones will begin forwarding a copy of every SMS message (e.g., text message) that the phone receives to your email account. This feature will vary from phone to phone.

        • Use this link to control this setting.
      • The Outlook apps for iOS and Android have some inconsistencies depending on version.

        • When using Outlook for iOS on iOS 9.2.1 devices, you are not able to edit recurring events. These events must be edited in a desktop client or the web client. Single events can be edited successfully.
        • When using Outlook for Android on Android OS 5.5.1 devices, clicking on and copying links sent in email messages doesn't always allow for a new window to appear or for the link to be copied.
      • In Outlook for Android, when viewing the calendar, the only calendar that is selected is the primary calendar even though other additional calendars were selected previously.

      Outlook on the web

      • Users were redirected to Microsoft login screen after selecting their Office 365 account from within My UW portal.

        • Workarounds:
          • Enter your within the username field on the Microsoft login screen and click Tab key. This will automatically redirect you to Outlook on the web.
          • Clear your cache/cookies and try again.
          • Use a different browser.
      • "500 Error" when attempting to set Public permissions for a resource calendar

        • Workaround described here.
      • Unable to use the menu bar to move through dates in Firefox versions 28, 29, and 30

        • Within calendar, when users tried to use the menu at the top of the calendar to move back or forward through the time ranges, you can only go forward or back once.
        • After that users can't change the time frame, using the arrows on the menus bar or by clicking on the date range links.
        • Depending on the view, the weeks, days or months do not change when a user clicked on either the left or right arrow.
      • Critical error when creating inbox rules with Google Chrome

        • In previous iterations of Outlook on the web, Google Chrome users would see a "Critical error" message when attempting to create inbox rules using "It was received from..." or or "It was sent to..."
        • Within newer versions of Outlook on the web, creating inbox rules in Google Chrome works correctly. However, Outlook on the web still contains an Other menu within the options menu, which allows you to access the old method of creating an inbox rule. Using this method will still result in an error.
        • Most UW-Madison users should have been moved to a newer version of Outlook on the web -- however, if you experience this error, you will need to use another browser or a desktop client to create your inbox rule.

      Apple Mail

      • There was an issue with Apple Mail (on all Mac OS | iOS versions) when attempting to configure Office 365 accounts. While it did not affect all Office 365 accounts, many users who attempted to configure their Office 365 account would experience either a crash of the Apple Mail program with a detailed crash report and an error message 'Mail quit unexpectedly', or an error message 'There was an error in the internet preferences pane', or you are required to enter additional server information. Apple provided an OS patch that increased compatibility with Microsoft Exchange but provided no information beyond basic patch notes indicating that a bug had been fixed. After the patch was applied users reported the error was resolved. There was a known workaround for users detailed below:

        Using our documented Configuration Instructions for Apple Mail, on step 4 enter an INCORRECT password and press the 'continue' option twice until it brings you to a second page. One the second page, leaving everything else the exact same, enter in the server field and press continue. The account will be broken initially because it has the wrong password, but it will allow you to complete the configuration process. Once the account is configured, and with the mail program up, from the top of your screen choose Mail -> from the drop-down list choose Preferences -> and from the list of tabs across the top choose Accounts. On the following page, find the password field near the bottom, erase it, and enter the correct password. In addition, add to the NetID listed in the username field. Once this is complete and you've saved your settings, your Apple Mail program will be configured correctly.
