Enable Datacenter Activation Coordination (DAC) Mode in Exchange 2010 DAG Datacenter Activation Coordination (DAC) Mode is a property of a DAG which can be turned on or off. DAC mode is disabled by default and should only be enabled for DAGs with three or more DAG members that have been deployed in a multi-datacenter configuration. DAC mode shouldn’t be enabled for In case you try to turn on DAC where it is not supported, an error will be returned.

Topic Last Modified: 2014-07-14 Datacenter Activation Coordination (DAC) mode is a property of a database availability group (DAG). DAC mode is disabled by default but should be enabled for all DAGs with two or more members that use continuous replication. DAC mode shouldn't be enabled for DAGs that use third-party replication mode unless specified by the third-party vendor. DAC mode is used to control the database mount on startup behavior of a DAG.
In this article I want to discuss the Datacenter Activation Coordination DAC mode, set into datacenter activation mode, in Exchange 2010 SP1 DAC mode in a.
