Deleted Delegate

We have a user (Phil)  that had another user (Sharon) delegated in outlook to receive his meeting requests. Now Sharon has left and her account has been deleted.

Whenever anyone sends a meeting request to Phil in Outlook, there is a non-deliverable response sent back from Sharon automatically, see below. How can we remove this account (its not listed as a delegate in Outlook anymore).

You can use the MAPI Editor to remove the hidden rule that gets created when a delegate is added to a mailbox.

How to delete corrupted and hidden rules from a single mailbox in Outlook 2003

Thanks for this suggestion I had already tried that and it did not work. In fact I have just discovered the /cleanrules command line switch for Outlook and this did the trick!

Self close, points refund please.
Straight dope and usage from Microsoft for future reference:


Run the Outlook /Cleanrules Switch
1.      Click Start, and then click Run.
2.      Type a quotation mark, type the path of the Outlook.exe file that you noted in the "Determine the Location of the Outlook.exe File" steps earlier in this article, type a quotation mark, type a space, and then type/cleanrules.

For example, if Outlook.exe is in the default location, the command looks similar to the following: "c:\program files\microsoft office\office11\outlook.exe" /cleanrules
3.      Click OK. Outlook starts and the rules are cleared from Rules and Alerts.

Or you could just remove the delegate from ADUC, Exchange general tab, delivery options... in the send on behalf section, 'remove'.
