tempting to mount the database. The error can be ignored and the mount allowed if Mount-Database is reissued with the -Force switch.

  2. Net start ClusSvc /forcequorum

Run the following in Exchange PowerShell:

  1. Start-DatabaseAvailabilityGroup -Identity LAZYDAG01 -MailboxServer EX01.thatlazyadmin.com

Hope this helps the next person and saves some time.
