This article covers how to add an additional mailbox to a primary mailbox account in your Outlook desktop application, after being granted delegate access by a mailbox owner. The shared folder(s) will appear in your mailbox folder list.

As a delegate, you are given rights to access shared data by the mailbox owner without the use of a password.
