Do you set up mailbox databases per mailbox server? i.e. DB1 on Server1, and DB2 on Server2 with new user mailboxes assigned to one or the other?
Or should both mailbox server see the mailbox DB on a shared disk in case one fails?
At the moment, looks like we've got one server with a few mailbox DBs, then another server with a few mailbox DBs. All named the same which is confusing.
