Since installing CU3 on a perfectly functioning server which had been running CU1 I have had to write a script and add it as a scheduled task to restart the transport service every 15 minutes otherwise incoming email just stops. The only errors I can see are related to performance counters.
I have now tried to install CU3 on a new server but it created 3 mailbox databases and all are dismounted and when trying to create another one I get this error:
Database is expected to be in a database availability group but the value for its MasterServerOrAvailabilityGroup property is not valid
So on this new server I can't even create any mailboxes.
Should I set up another server on CU1 again?
Thanks
