  2. Tap the Add Account button in the left navigation pane, then tap Add a Shared Mailbox. 
    Add an account to the Outlook app

  3. If you have multiple accounts in Outlook Mobile, select the account that has permissions to access the shared mailbox.

Access via a macOS device

Open a Shared or Delegated Mailbox

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.

To open the shared mailbox:

  1. In the Tools menu, choose Accounts, and select the account that has access to the mailbox.

  2. Select Delegation and Sharing

  3. Choose Shared With Me tab

  4. 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.

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