How to remove or update rules from older versions of Outlook?

I somehow have a rule that's filtering important messages to a weird folder, but there are no visible rules that match that folder. But there is a warning sign that says:

There are rules created with a different version of Outlook or Outlook Web Access that are not shown.

How do I delete or modify those rules?


Log into Outlook Web Access. Select Options then All Options (or whatever it might be called), Organize E-Mail and then Inbox Rules.

I had rules listed here, not listed in Outlook proper.
