Maaaan! I was suffering too much, and i've found god damn solution finally!
So: I have 2 PCs: XP (Primary), Vista (Secondary)
The problem appeared when i upgraded my QTEK9100 from WM5 to WM6.1.
I had to recheck my contacts and my calendar EVERYTIME when i moved from one PC to other!!! It made me stop syncing my Vista PC!
Now i solved it this way:
1) I prepared my Primary PC's PIM, verified that all actual and necessary contacts and calendar events on my Primary PC (XP). For further correct work i had to remove all duplicate recuring events - especially contact BirthDay's events, that were created automatically.
2) I synced my PPC on primary PC (XP).
3) I unchecked my contacts and calendar on secondary PC(Vista), and verified that there is no sync errors.
4) I DELETED all contacts and calendar events in outlook on Secondary PC(Vista) - nothing to loose, because all necessary information is on Primary PC(XP).
5) I checked contacts and calendar to sync on SecondaryPC (Vista). While syncing WMC copied all contacts and calendar events from PPC to SecondaryPC's PIM. There appeared few error messages on syncing calendar Birthday Events with link to these events. I was iteratively DELETING birthday events on PPC and on SecondaryPC's PIM that caused errors, until it was successfully synced on Secondary PC(Vista)
NOW IT FINALLY WORKS OK EVERYWHERE! Now I don't need to recheck calendar and contacts in WMC or ActiveSync, everytime i move my PPC from one sync-PC to another!
If you want to thank me - just make me rich! :)))
