Exch 2K SP2 and Rule limitations

I have a user who gets quite a bit of mail and uses rules to keeps his inbox organized. We seem to have hit a rule limit of about 50 separate rules. I’m looking for some way to increase or remove this limit. I’ve search technet and my reference docsand can’t seem to find this limit mentioned anywhere.

There are no space restrictions in effect on the server or this user.

TIA,

Fred Buecker
