Sync: 100s of changes when I've made none

[pbanman]

When I sync my contacts and calendar with outlook it is telling me there are 200 and some changes to the contacts when in reality I haven't made any changes. This happens with the calendar too.

What I've tried is wiping all the calendars and contacts from the blackberry and then syncing it with outlook. The initial sync works fine, but the next time I plug it in it will say there are a bunch of changes.

The blackberry is set to keep all calendar entries and autoarchiving is turned off in outlook. The same thing happened when I went to a brand new Bold 9900 so it can't be a problem with the phone itself.
