User has been having sync issues for months now on 2 separate machines: Win XP & Win 7. Email that has been filed away in specific folders finds it way back into the inbox. It is usually old email and it finds it way to the top of the inbox.
Profile has been recreated and updates have been installed. Took her off 'Cached Exchange Mode' as well, no luck. Problem usually goes away after restarting Outlook, but not always.
Logs and troubleshooting on Exchange 2010 seem fine according to colleague (I don't have access). Any ideas or advice for basic troubleshooting procedures?
