We currently have 2 Exchange 2007 servers. Server A hosts the HT, CAS and MB roles and Server B hosts MB role only. The plan is to move all mailboxes onto Server B. This process is almost complete. This will leave a large empty MB Database/Storage Group. We would still like to retain the mb db. Is there any way that this can be reduced in size, or removed and recreated. Space is an issue on this machine, which is what is driving the move.
Also, is it possible to install the remaining roles onto server b , but not have them active.
Any help would be appreciated.
