I am experiencing the same problem as the original poster (4.2sp1 and Outlook 2007), and his solution only SOMETIMES seems to correct the issue FOR ONE SYNC, then the problem returns.

Specifically, my calendar sync is dying on some particular calendar entry. I've done all of the standard debugging and logging. I've gone so far as to copy all of my appointments out and then back into my calendar. I've opened all calendar items, clicked the Recurrence button, and saved each and every calendar item. I've even viewed the calendar in Detail view and added all of the data fields to the view and corrected all of the minor little inconsistencies in them. Oh, AND I'VE DONE ALL OF THIS THREE SEPERATE TIMES! This method also seems to have the end result of letting my BB sync a few times, but then something breaks and I either have to recreate the calendar items again OR do as the original poster suggested. This is really silly.
