Additionally, many times an Email administrator will be faced with the task of gathering and producing messages for legal cases. For these reasons, message Archiving is a vital process.
I had a situation where my test environment DAG was offline and not detected. I’m not sure what caused this issue, however the mailbox databases were dismounted and the Content Indexes were in a failed state.
