View an Additional Mailbox

You can add additional mailboxes to Outlook if you have permission to access those mailboxes.

1. Open Outlook
2. File -> Open -> Other User's Folder
3. Search for the desired (arbor) email and select inbox in the drop-down menu
4. Press Open
5. Restart Outlook

It takes a couple of minutes to populate the mailbox and its contents once Outlook is opened again.
