Open a Shared Mailbox in Outlook for Mac

In Microsoft 365 Exchange Online, a Shared Mailbox can be created that allows any number of added users the ability to have it open and available to review with Outlook.

On Windows, Outlook usually adds any additional Shared Mailboxes that a user's has been granted access to automatically.

On Macintosh, Outlook does not perform this automatic task and a user needs to add it manually.

Open a Shared Mailbox

1. Open Outlook for Mac, then click the File menu, Open, then Shared Mailbox.
   
   
2. Enter the full email address of the Shared Mailbox you have access to, then click OK.

Shortly, the Shared Mailbox will appear and can be reviewed like other mailboxes.
