Issue when creating a DAG with Exchange 2013

A server-side database availability group administrative operation failed. Error The operation failed. CreateCluster errors may result from incorrectly configured static addresses. Error: An error occurred while attempting a cluster operation. Error: Cluster API ‘”CreateCluster() failed with 0×5. Error: Access is denied”‘failed. [Server:]

the ECP wizard tried to add the first mailbox server to the DAG. During this process the wizard create a computer object in Active Directory (the CNO). This object don’t have the good rights. Exchange Trusted Subsystem had special permissions assigned and not “Full Control” on CNO.

Assign “Full Control” to Exchange Trusted Subsystem on the CNO.
