MSExchangeMailboxReplication Service will not start

After attempting to install Security Update For Exchange Server 2016 CU15 (KB4540123) on our Exchange 2016 Server CU 15 Version 15.1 (Build 1913.5) which failed to install it disabled all the Exchange Services.  One of the Servers was able to get all the services back up running but the other unable to get the MSExchangeMailboxReplication Service to run. Get the message "the microsoft exchange mailbox replication service on local computer started and then stopped" Have fun through the https://docs.microsoft.com/en-us/exchange/management/health/troubleshooting-mrs-health-set

and searched the web for solution.

 

When run the Get Server Health is showing some of the MRS are unhealthy

this is stopping any mailbox moves for this server. 

 

Has anyone come across this or know how to resolve this?

      farismalaeb thanks for your reply

       

      The only windows event log I can find around the service are under Applications and Services Logs > Microsoft > Exchange > Managed Availability. 

      * Monitoring

      * RecoveryActionLogs

      * RecoveryActionResults

       

      attached is the word doc with them in it hopefully it helps

        To get more logs you need to run the following PowerShell command

        Get-EventlogLevel -Identity "MSExchange Mailbox Replication\*" | Set-EventlogLevel -Level Expert

         Then restart the service and post the logs

        I think they will be in the Application event log
