I have an issue. My Treo 700wx was working properly. My Outlook email and calendar were in sync. Something happened and my calendar was out of sync. I removed the settings on the phone for the exchange sync. This removed my email but did not remove my calendar items. I did a hard reset and configured the active sync setting and now it will only sync new items email/calendar. It looks like it sees all of the items because I can see the number of items when it runs the sync. It looks like it is remembering the items that had already been in sync and will not do them again.
Thanks
