That has happened to me several times. Sometimes after a hard reset, sometimes after playing around with ActiveSync, when setting up GoogleSync or when trying to sync two computers on different windows versions. I have also had issues with duplicate contact lists. It has to do with ActiveSync lousy profile handling. Also the Facebook Integration causes birthdays to get duplicated - and you might end up having those 4 times or more. I also have had problems with appointments that never sync. I use two programs: Pocket Mechanic on the TP2 (a great little app that has a 30 days free trial but I ended up purchasing) and ODIR (free from Vaita) on the outlook side. If you go the ODIR way and if you are on a server, switch to offline mode before using otherwise will hang. For appointmets that never sync - either delete them or edit them. For some reason some all-day appointments get the start and end times reversed thus creating errors for appointments that finish before they start. Unfortunatedly you'll have to this one-by-one. Bottomline - ActiveSync is not great but not much of a choice if u are on XP.

Some posts will recommend deleting the relationship - I will advise against this. While it will in fact fix the relationship problems, ActiveSync may may feel like deleting everything.
