Hi everyone, I'm decommissioning my mailbox servers since we migrated our mailboxes to Office 365. I removed the first mailbox server but while trying to remove the second mailbox role, I receive:
The following servers in the Windows Failover Cluster are
not in Active Directory: dc-exmb01. This is usually the result of an incomplete
membership change (add or remove) of the database availabilty group
Not sure how to go about this. Any idea?
