This article describes the process to open and edit shared mailboxes from the Outlook Web App. These steps will work regardless of which web browser you are using.

Opening a Shared Mailbox

2. In the Open another mailbox window, type the shared mailbox's full email address (i.e., mailbox@uwm.edu) and click Search Directory (if you've opened this mailbox before, the name should appear as you type).

3. Select the mailbox you wish to open from the menu.

4. Click Open and the shared mailbox will open in another browser tab.

5. View and send emails for your shared mailbox in the new tab.

Note: If the user does not have permission to access that mailbox they will receive two possible error messages:
  •  A blank screen with the words Bad request.
  •  An error message stating: You don't have permission to open this mailbox. (This may appear after the first error message if the user attempts to enter the mailbox again.)
