The update on the test machine went well but it still is having issues with the Outlook integration.
This was an upgrade so I am going to do a clean sheet installation on another spare PC to see if it is legacy issues causing the problem.
Another thing that i tried is that as this was not a schema change I tested cross version sync but it failed as it dropped the connection with a lost connection message rather than the version mismatch error message which it would normally generate. So as expected all sync versions need to be upgraded t the same time as the server.
