Since installing Cumulative Update 10 on my Exchange Server 2010 SP3 system, I have experienced two events that have impacted my users with ActiveSync. Apparently, after the update, ActiveSync will try to open a single person's mailbox (called firstname lastname in the error data) and is unable to do so. ActiveSync thinks the server is unavailable due to load (it is not) and turns off ActiveSync for 60 seconds. When ActiveSync turns back on after 60 seconds, all ActiveSync users receive all of their messages again on their devices. The event occurs every 10 minutes until ActiveSync is turned off for the user firstname lastname. Additionally, I turn off IMAP and POP3 for firstname lastname. ActiveSync no longer reports th error and all is well. After deleting the devices from firstname lastname's account, the devices resync with ActiveSync and no longer have the problem.
I have never had this problem before the update. I have two questions:
1) Can I change the timeout to a very short number?
2) Is this problem due to Cumulative Update 10?
Below is the data from the event logs for Event ID 1016 (with personally identifiable info changed):Alert: Active Sync is temporarily suspending requests to an unresponsive mailbox server. Users with mailboxes on this server may not be able to sync until the server recovers.

data on Mailbox server [SSS-CAT-DB01.domain.com]. It will temporarily stop making requests to the Mailbox server for [60] seconds to reduce load on that server. This delay may occur if the Mailbox server is overloaded. If this event is logged frequently, review
the Application log on this server and the Mailbox server noted above for other events that could indicate the root cause of performance problems.
