    If you have an even number of Exchange Servers is a DAG, then you MUST have a Witness Server, otherwise the DAG is not configured correctly.

    I would:

    Run these commands:


    If those look good.

    Dismount the databases

    Shut the Servers off.

    Then once , done

    Restart all the servers and File Share Witness

    Wait a few minutes.

    Check the event logs on the Exchange Servers for anything unusual

    Run those powershell commands again:


    The mount the databases.

    Wait a few minutes:

    Run again:

    Hi @JustinMicheal-7973

    The commands are used to check the status for your server and database copies, the mainly steps like below:

    1.Shut down servers:

    1) Shutdown CAS servers except CAS server which is configured as FSW server.

    2) Dismount the databases to prevent switchover to the second node when shutting down.

    3) Shutdown the passive Mailbox servers first then shutdown active Mailbox servers.

    4) Shutdown the File Share Witness, then shut down AD.

    2.Start up the servers:

    1) Switch on AD and make sure it is running normally in your site.

    2) Switch on File share witness server.

    3) Start the CAS servers.

    4) Start the passive mailbox servers, then start the active mailbox servers.

    5) Finally, start reset one by one and mount the database
