I am sure someone else has asked this, but have not been able to find it.
We are getting ready to replace our current Exchange 2003 server with a new 2003 server. Exhcange is being installed and then user mailboxes will be moved from the old server to the new server. Can Unity be point to both Exhcange server and individual users moved as their mailbox is moved or do all mailboxes have to be moved at once? Also, what do I need to do to add the new exchange server to Unity?
