Adding a shared Exchange Online mailbox to Outlook for macOS

You can add a shared Exchange Online mailbox to your Outlook app on macOS desktops and laptops.

     'New Outlook' doesn't currently support shared mailboxes

Outlook for Mac has an option to use 'New Outlook'. This version doesn't currently support shared mailboxes, so you'll need to leave this turned 'Off' if you need to use them.

Before you begin:

You'll need to have your main account or the account with permissions to the shared mailbox already set up within Outlook for Mac.

Your shared mailbox will now be listed in Outlook's mailbox pane.

 

Alternative method

Alternatively, you can open another mailbox (providing you have permission to do so), via the File > Open > Other User's Folder menu item. From the search box that appears, search and choose the required mailbox, choose what you want to open (for example, Inbox) and click Open. This will open just the inbox of the added mailbox, adding it into the mailbox pane list.
