When editing synced contact, exchange prompt ‘update the contact version’

This typically occurs after an upgrading from Exchange 2007. The synced contacts were created when Exchange 2007 was in use. Exchange is then upgraded to a newer version. If you attempt to view/change the Exchange contact, you get a prompt indicating you must ‘update the contact version’.

We have found that setting msExchVersion to a specific value on the affected contacts fixes the problem. So, if you add this setting to a custom map file, this should resolve the problem.

NOTE: You should manually test this by editing the attribute manually in AD U&C. Further, we recommend you set up a test connection to verify your results against a few test objects

1. If you do not have a custom object map file, create one per this KB

2. Add this mapping:
   msExchVersion=44220983382016

3. Run your test connection Discovery and Sim. You can expect to see most/all objects modified on Sim.

4. Check the contact to confirm the problem is resolved.
