I have a client who is using a Treo 650 with Sprint. When he sync's up his email with our corporate Exchange server, the Treo downloads already read email, as well as emails that have been marked for deletion (moved to the deleted items folder) on his desktop Outlook 2002.

When we look on the Exchange server, what's in his Inbox and Deleted Items folder correspond to what we see on his desktop Outlook 2002 application. He is set for no caching of email through Outlook (2002 doesn't give you that option anyway).

A bit stumped. Any suggestions on what to look for, what to change?
