We have one user that uses the Treo700w and uses the Activesync to sync directly with our mail server. Other users do this with no problem and other users could be setup on this device and work just fine. This one user, when he syncs, the calendar pulls up items from six years ago, marks them with today's date in the Treo and then proceeds to sync them into his calendar for today. Some of the items don't even look to be his, and we are talking thousands of items, it is almost as if he is syncing the entire agency's worth of calendar items past and present, or at least those of several other people. I'm thinking this is an issue with his Exchange account (2K3 Server/Exchange setup).
