There are two ways to add a shared mailbox in Outlook (Duke-supported versions of Outlook). This KB is to distinguish the differences/ advantages of using one way over the other, and then instruct a user how to connect a shared mailbox using either way.

How To Add Another Inbox To Outlook

The first option will add the mailbox more for viewing purposes. You will be able to read email from the shared mailbox but whenever you want to send an email 'from' the shared mail box, you would always have to click on 'from' button and drop the box down from your personal email to the shared mailbox email. Also, your shared mailbox sent mail and deleted mail will always be in your personal sent and deleted mail folders.

The second option will add the mailbox so that you are 'acting' as this particular mailbox. If you are in the shared mailbox for example, the 'from' field will automatically default to the shared mailbox (no manual drop-down necessary) and the sent and deleted items will show up in the shared mailbox's sent and deleted item folders instead of your personal sent and deleted items folders.
