Microsoft 365 - Accessing a Shared Mailbox or Service Account on the Web

How to open a shared mailbox or service account in Outlook on the web.

In order to complete these steps for a particular account, you have full mailbox access to that account. If you are unable to complete these steps or need assistance, please contact Technical Support.

Shared Folder Method

This option adds the email address as a secondary account accessible alongside your NetID account.

  1. Log in to https://email.wisc.edu.
  2. In the top-right of the window, click the Settings Gear icon indicating settings button button.
  3. Navigate to Account > Shared with me.
  4. Click the + Add button.
  5. Enter the email address you'd like to map.

    If the address doesn't show up in your search, please contact Technical Support.

  6. Select the email address from the dropdown.
  7. Click Continue.
  8. Click Close and close the settings window.

The account will appear at the bottom of your folder list.

Open Another Mailbox Method

This option opens the account directly. In most cases, the shared folder method above is more convenient.

  1. Log in to https://email.wisc.edu.
  2. Click the account menu in the top right. If you have a profile picture, the menu button will show it. Otherwise, it should show your initials.
  3. Select Open another mailbox.
  4. Enter the full email address of the account you'd like to access.
  5. If the account shows up in the search results, select it. Otherwise, click Use this address in the results dropdown.
  6. Click Open.
