Question:
In our organization, some employees belong to a group mailbox. Is it possible to open multiple mailboxes (including some shared ones) from a single Exchange profile?
Answer:
You can add mailboxes to a profile in Outlook by selecting Tools | Services | Exchange Server Service | Properties. On the Advanced Tab, add as many mailboxes as you like.
Naturally, the user will have to have appropriate permissions to that mailbox to open it.
