When you do maintenance on an Exchange server, you would expect everything to be fine after a reboot? Correct? Well in some cases that does not happen.

For example, one of my Database availability Groups (DAG) had the passive copy all in a Suspended state. How do you check the DAG status?

  • Get-mailboxdatabasecopystatus *

To fix this, you can run a simple command to resume the mailbox database copy:

  • Resume-MailboxDatabaseCopy -Identity “DAG1-STORE1\MB01”

The command will run and then you will be back at the next line within the Exchange Management Shell (EMS). When you check your DAG again, all should be healthy. If not, then check the event logs for any errors.

Hope it helps.
