Configure activation policy for a mailbox database copy
Applies to: Exchange Server 2016
Topic Last Modified: 2016-06-14
Summary: About activation policies in Exchange 2016, and how to configure them on mailbox database copies.
Activation is the process of changing a mailbox database copy from a passive copy to an active copy. Activation can occur automatically (by the system as part of a database or server failover operation) or it can be performed manually (by an administrator 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.
