Configure Manuel Failover for Entire Mailbox Server
Let?s say you want to disable entire DAG member node from being considered in the Automatic Activation Process. In other words, you want to configure manual failover for DAG member. You can use the following command to prevent any databases on a specific mailbox server in DAG from being considered in the Automatic Activation (automatic failover) Process:
Set-MailboxServer -Identity MailboxServerName -DatabaseCopyAutoActivationPolicy Blocked
To allow database copies to be activated again, I would replace ?Blocked? with ?Unrestricted?:
Set-MailboxServer -Identity MailboxServerName -DatabaseCopyAutoActivationPolicy Unrestricted
