Open a shared folder or mailbox in Outlook for Mac

If you have been granted access to another mailbox, either another persons mailbox or a shared email account, use these steps to add that account to your Outlook for Mac.

What is this?

Use this method if you are a delegate for another user's mailbox or when you have permissions to several folders in a shared mailbox.

You can also use this method when you have full access permissions to a mailbox.

Instructions

To open the shared mailbox:

1. On the Tools menu, click Accounts  > Advanced > Delegates.

2. Add the mailbox under Open these additional mailboxes

 

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.

 

Notes: 

• When you use any of these methods, the shared mailbox account is added as an option in the From field when you compose emails. This lets you select the account in the From field regardless of whether you have permissions to send from this account. If you do not have "Send As" or "Send On Behalf of" permissions for the account, email from the account will not be sent.
