Outlook (Mac) - How to Add a Shared Mailbox to Outlook for Mac

Prerequisites

Before following these steps, ensure that you have already configured Microsoft Outlook for Mac to access your Office 365 mailbox. If you have not completed this setup, please contact the ITS Help Desk for assistance.

Adding a Shared Mailbox

Follow these steps to add a shared mailbox to your Exchange account in Microsoft Outlook for Mac:

1. With Outlook open, click on Tools in the menu bar at the top of your screen, then select Accounts.
2. In the Accounts window that opens, ensure your Exchange account is highlighted on the left side, then click the Advanced button in the bottom right corner of the window.
3. At the top of the Advanced settings window, you will see three tabs. Select the Delegates tab in the middle.
4. In the bottom section of the Delegates screen, locate the area labeled "Open these additional mailboxes:" and click the small + button below it.
5. In the search box that appears, type the email address of the shared mailbox you want to add. Once you locate the correct mailbox, click Add.
6. Click OK to close each dialog window until you return to your inbox.

Viewing Your Shared Mailbox

The shared mailbox should appear in the folder list on the left side of the Outlook window within a few moments. If the shared mailbox does not appear after several minutes:

1. Quit Microsoft Outlook completely.
2. Reopen Microsoft Outlook.
3. Check the folder list on the left side of the screen for the shared mailbox.

Troubleshooting

If the shared mailbox still does not appear after restarting Outlook, verify that you have been granted access to the mailbox. Contact the ITS Help Desk if you continue to experience issues.
