We were faced with a nice little challenge recently here.
The normal rule about mailboxes in Exchange is simple and fairly obvious: one user, one mailbox, and vice versa.
Or that's what I always learned...

Now, we have an account which normally logs in 2 or more times (our reception desk).
Since they log in with one account, they share a mailbox, simple as that.

Now, for our new VoiP system, these accounts need to be split up. Every phone needs a different user (at least in the setup we use).

There is a simple solution to this:

- Create the extra account(s).
- Do not mail enable this account.
- Grant this account full access & send-as permissions on the mailbox you need.
- in the Email field in AD Users & Computers, type the email address of the mailbox you want to open.
- Open outlook, auto discovery will automatically open the correct mailbox for you.
