I searched for this first, and couldn't find any relevant threads so...How do you associate a disconnected mailbox in Exchange Server 2003 with a new Domain User Account that has no mailbox association? Thanks for any help.

You can only do this once the mailbox has been marked as deleted. If the mailbox does not have a red and white "X" over it, right click on the Mailboxes container under the mailbox store and choose Run Cleanup Agent. To associate the mailbox, right click on the deleted mailbox and choose Reconnect. You will be prompted to search for a user account that does not have a mailbox.

Thank you Jim. Worked like a charm.
