Suspend Multiple Database Copies

If you are doing maintenance on a server and want to suspend all database copies on that server (assuming none are mounted) it is very simple and all you have to do is run:

Get-MailboxDatabaseCopyStatus -Server | Suspend-MailboxDatabaseCopy -Confirm:$False

If you want to suspend all copies of a particular database (except the one that is mounted of course) across all servers you can simply run:

Get-MailboxDatabaseCopyStatus | Suspend-MailboxDatabaseCopy

And ignore the “The suspend operation can’t proceed because database ” on Exchange Mailbox server ” is the active mailbox database copy.” error message.

But what if you just want to suspend the 4^th copy of all your databases across all your servers? In this case, we will have to use the following script:

$dbs = Get-MailboxDatabase

ForEach ($db in $dbs) {

      ForEach ($dbCopy in $db.DatabaseCopies) {

            If ($dbCopy.ActivationPreference -eq 4) {

                  Suspend-MailboxDatabaseCopy $dbCopy.Identity -Confirm:$False

            }

      }

}
