Deleting rules for a disabled user account.

Recently our security team asked me if we could delete the rules (server- and client-side) on a mailbox when a user account is disable.  After some research, I found the following utilities, but my conclusion is that there is no easy way of removing rules when a users is disabled.

Options:

1. Login to the account and delete the rules
2. Use MFCMAPI.exe (http://support.microsoft.com/kb/924297)
3.  Use Mdbvu32 (http://support.microsoft.com/kb/320022)
