Simple fix for a corrupted Date Book sync error (at least it worked for me on my Treo 650).
1). Turn off 'Show Calendar Event' in the Phones 'Options - General Preferences' menu.
2). Turn off phone.
3). Set the Date/Time to the maximum limits (12/31/31) in Preferences.
4). Open the Calendar and view the maximum day 12/31/31.
5). Select 'Purge - (Delete events older then 1 week)' in the Calendars Options menu.
6). Reset the Date/Time to the current day in Preferences.
7). Hotsync (Desktop Calendar overwrites handheld).
8). Hotsync again to make sure you don’t get the error (Synchronize the files).
That’s it.
