Outlook Rule Problem

Outlook 2003 client. Exchange 2003 infrastructu

I have a client-side rule to filter mail into a specific
folder. This rule has not worked since I moved to
Outlook 2003. If I run the rule manually, it works fine,
even if I run all of the other rules manually as well (so
I know an earlier rule is not breaking this one).

Problem happens from both my work laptop, and from my
home PC (also running Outlook 2003).

Can someone tell me if I can enable a rules log file or
something, that lets me see what rules run against each
incoming email? Has anyone else seen this before?
