I have had this exact problem except on a Vista and here is the funny part, it has nothing to do with your OS. Its a freakin 2007 issue with its "wonderful" security crap that acts funny.

I honestly don't know how to help you with that on XP since I was told basically by M$ to "just upgrade to vista and use WMDC and you will be fine" which is the biggest load of crap tech support can shovel your way.

So I moved it from my desktop running XP MCE to my laptop running vista x64 ultimate and upgraded the WMDC software and set it up and to no freakin surprise, it didn't work. So I contacted them back and told them that they are full of $hi* and they said that somehow I corrupted the partnership.

So I followed these instructions and it worked (but it was on vista using WMDC instead of ActiveSync). 1) delete relationships and remove all backup and old profile files. 2) reset your phone to original factory default so it has no settings on it. 3) make sure you have your outlook OPEN and logged in and whatever, 4) connect the phone and follow instructions to setup a partnership (with outlook open) and then the permissions will setup right to communicate. It might prompt you for passwords if your PST is password protected and I would recommend telling the sync to remember the password. That's it.

Good luck and and hope it works for you.
