Consider the following scenario:
- You have a Microsoft Exchange Server 2010 server that is configured as follows:
- The target mailbox database has a passive copy.
- The DataMoveReplicationConstraint property on the target mailbox database is set to something other than None.
For more information about how the DataMoveReplicationConstraint property works, see Exchange 2010 Mailbox Moves and Mailbox Resiliency. - The mailbox server that hosts the passive copy has the DatabaseCopyAutoActivationPolicy property set to Blocked.
- You install the Service Pack 3 Rollup Update 3 (KB2891587) for Exchange Server 2010.
