Activation is the process of changing a mailbox database copy from a passive copy to an active copy. Activation occurs automatically as part of a database or server failover operation, and it can be performed manually as part of a database or server switchover operation. Blocking a database for activation prevents it from becoming the active copy during a database or server failover.
