The problem I have with offline files synchronising whenever *anyone* logs off the computer is documented at kbAlertz which although doesn’t reference the site, can be found at KB article 811660). Annoyingly it looks like a call needs to be placed with Microsoft to get this hotfix – or wait until service pack 2 (I guess). Although it doesn’t bother me too much it does annoy the other people in the office when I log onto their computer 🙂
