Hello,
We have Exchange 2007, and we've deployed Exchange 2013 and coexistence appears to be working. We have done a small pilot migration of 11 users, and I have 2 of those users that are not able to get iPhone/ActiveSync working. OWA and Outlook access work without a problem. https://testconnectivity.microsoft.com/ is telling me "The test of the FolderSync command failed." and "Exchange ActiveSync returned an HTTP 500 response (Internal Server Error)"
The error I'm receiving on the mailbox server event log is:
An exception occurred and was handled by Exchange ActiveSync. This may have been caused by an outdated or corrupted Exchange ActiveSync device partnership. This can occur if a user tries to modify the same item from multiple computers. If this is the case,
Exchange ActiveSync will re-create the partnership with the device. Items will be updated at the next synchronization.

--- Exception start ---
Exception type: Microsoft.Exchange.AirSync.AirSyncPermanentException
Exception message: A null value was received for the NTSD security descriptor of container CN=ExchangeActiveSyncDevices,CN=LASTNAME\, FIRSTNAME.,OU=XXX,OU=People,DC=DOMAIN,DC=local.
Most articles I've found with this issue say to confirm that "Inherit parent permissions" is check on the AD object, but that is already checked?
The funny thing is that most of our pilot users don't have this issue. It is only for some of them.
Any help is appreciated.
