Open a Shared Mailbox in Outlook for Mac

Article Contents

The method can be used if you are a delegate managing another user’s mailbox or if you have access to more than one mailbox in a shared mailbox. This method is also useful when you have full permissions to access a mailbox.  

To open the shared mailbox:

  • In the Tools menu, choose Accounts, and select the account that has access to the mailbox.
  • Select Delegation and Sharing
  • Choose Shared With Me tab
  • Choose + to add a shared or delegated mailbox

Note:  If you have permissions to custom folders in the mailbox but not to the top-level mailbox folder, the custom folders will not appear in the folder list. Only default folders that you have permissions to, such as Inbox, Sent Items, Deleted Items, and Calendar, will appear in the folder list without top-level mailbox folder permissions.

Alternatively, you can also go to File > Open Shared Mailbox, to open a shared or delegated mailbox.
