I have done all the above things many times with no success.. still received the dreaded 0x80040fb3 until I finally told it
to do nothing with conflicting items... finally the sync worked...
The Blackberry is a strange device - it works for a while, then decides to delete all your previous calendar data... so now that I have actually synched the BB successfully, I have synched by iPod Touch to my Ouotlook calendar as a backup because the iPod ALWAYS works properly!
I have been using BB's for many years, and teach courses about them and find I spend a lot of time troubleshooting for people.. how depressing is that?
