How to Add a Shared Mailbox in Outlook (Windows & Mac)

A shared mailbox allows multiple users to read and send emails from a common address, such as [e-mail], [e-mail], or [e-mail].

Before you begin, make sure IT has granted you access. If access was recently assigned, wait a few minutes and restart Outlook.
