Using a Treo 650, my ActiveSync seems to synchronize everything except the sent email correctly. Admin documentation for ActiveSync w/Treo 650 & Exchange 2003 says,

"When a user synchronizes a Microsoft Exchange ActiveSync account, a copy
of any messages sent from the device is placed in the Sent Items folder on the
Exchange server. A copy of any messages deleted from the device are placed in the Deleted Items folder on the server.

Has anyone else experienced this problem and found a way to correct it?
