All clients or multiple clients

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

• Cannot respond to S/MIME encoded emails in Outlook on the web

  • Individuals who receive an email that is signed with a security certificate, may not be able to respond or forward that message when using the Outlook on the web client. The UW-Madison Office 365 team is working with Microsoft for a solution.

  • Workaround: Use a desktop client to answer S/MIME encoded email.

• Cannot print calendar in Outlook on the web's new interface as of 09/2019. Per Microsoft, this is known behavior/issue.

  • Workaround 1: Print calendar using the browser option instead of using the print option in Outlook on the Web.

  • Workaround 2: Save the calendar as a PDF using Internet Explore and then print the calendar events.

  • Microsoft recommends voting for the option to print calendars in Outlook on the web's new interface here: https://office365.uservoice.com/forums/264636-general/suggestions/38460925-not-printing-details-of-the-meetings-calendar.

• 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

  • This only occurs only if the resource calendar is invited to the event. If the event is scheduled on behalf of the resource -- i.e., the resource calendar creates the meeting -- this will not occur.

  • Microsoft is aware of this issue and has stated that the feature is working as designed.

  • There are two ways to work around this issue:

    • Use the resource calendar to create the meeting. In order to do this, you will need at least read and write permissions to the resource. Select your client below for instructions:

      • Office 365 (Outlook on the web | Outlook for Windows/MacOS) - Work On Behalf of a Resource Calendar
        

    • Disable auto-accept for the resource calendar:

      • Office 365 - Configure Resource Scheduling Options/Settings/Permissions
        

• 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 "@groups.wisc.edu" 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 anr 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

  • Some users may experience an issue with resource calendars not processing event invites and cancellations appropriately, even if the setting is selected to do so.
  • Our current work around for this issue can be found here: Office 365 - Resource Calendar Not Automatically Processing 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 desktop client, 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.

• 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/logged in with.

• Unable to log into Outlook on the web via Safari browser on MacOS Mojave - may receive "We couldn't sign you in. Please try again"

  • We are currently working with Microsoft to further troubleshoot the issue.
