Q10 Syncing issue if not used overnight - iPad and S3 OK

Have a user on a Q10 reporting the following issue.

"Good morning ...virtually every morning I have a synching issue with my BB, emails are flowing fine all day but stop overnight. To start mail flowing again I fix it by a combination of resetting the Hub, sometimes 2-3 times, resetting BB, only when he send several new emails to myself after some time they start to flow....sometimes it take 30-40mins."

He is connected to a SBS 2011/ Exchange 2010 server via ActiveSync on the Q10, and has a S3 and iPad configured on the same Exchange Account to the same exchange server and these devices are working fine 100% fine, both sending and receipting as they should. All other users on iPhone's are fine too.

Apparently its running latest firmware V10-4181, I don't have any other users on Q10 so looking for any advice as it point to an issue on the device.

I am not seeing that issue on my Q10 and Z10's. However, it looks like you are using straight Active Sync and not routing through a BB server, is that correct? Does the user see any errors? Are there any errors for the user on the Exchange server around ActiveSync? Have you verified in the ECP that the device was approved? Exchange 2010 introduced ActiveSync blocking unless the device is approved.
