You don't mention what version of Outlook you're using or what type of email
environment you're in (POP3 or Exchange)?
Use the Mdbvue32 utility from the Exchange Server CD-ROM or
the Exchange Server service pack to view all the rules or download from here:
http://www.microsoft.com/downloads/...82-4C6E-4EC5-983E-127100D71376&displaylang=en
Export both the client and server user rules from Outlook for safe keeping,
then use MDB Viewer to manually remove all rules from the mailbox. To do
this:

13. Once you find the rule that you want to delete then close the properties
for that rule.

is still highlighted.
15. In the "Operations available (select operation, then push Call Function
button)" text box, push the drop down button to reveal the list of functions.
16. Scroll down the list of functions until you see "lpFld ->
deleteMessages() (ON SELECTED MSGS)" and then click on it to select it.

selected.
