Lync Persistent Chat Service Stopping – 53503 Unexpected DB Version

After I added the persistent chat role to a Standard Edition Front End Server the service was stopping unexpectedly.

There was an error in the event viewer 53503 Unexpected DB Version


I ran the Lync Update Installer and noticed that the persistent Chat role was not up to date


I started the persistent chat service again and the issue was resolved the service was starting and running. whoohoo!!! time for a brew !

So remember when adding Lync roles to run the appropriate cumulative update straight way !
