I run Exchange 2003 and have users on OWA. One user just got a new client machine running Windows 7 and Office 2010. Since the upgrade, her inbox in the OWA interface does not sync correctly with Outlook on her client machine. For example, she moved several emails from the inbox to folders and deleted several from her inbox from her client. Then she logs in remotely via OWA and all the emails she had moved or deleted on her client are still in the inbox.
