I have office 2003 (ran from group policy) and locally installed Outlook 2007. Since the days of '95 I have had the same account and created rules as and when. With each upgrade since then (XP, 2003) these rules have transferred across and worked fine.

After 1 week of 2007 I noticed the rules are no longer working, even if I go through the Rules assistant and check Run Rules Now.

I deleted all the rules (over 40 in total!) incase these was some conflict between versions and added the rules in again from scatch. They don't work. Nor will the run through Run Rules Now.

Any ideas what could be wrong? Occasionally when I start Outlook in the morning or try to open/save a calendar appointment a box pops up "trying to install 2003", this sticks until I click cancel as it never reaches the end.
