Hello,

I have an Exchange 2007 server with 2 Mailbox(Active / Passive) servers and 2 Hub/Cas Servers.

Each time I send an appointment to one user, I receive an error message like this :

So, I try to delete the AD user and to create a new one with the same mail adress.... I still have the problem after that !

I have to say that he receive the appointment correctly, but Exchange always send this error message...

Have you any Idea ?

Have a look at this article : http://teknologist.net/2010/list-delegates-in-exchange-2007/

'Ghost delegate' may generate NDR

There is some powershell command that may help you identify the problem

Thanks. I read your article but I don't find any "ghost delegate" on the account...

Now that you have removed and recreated the AD account, Outlook may be using an obsolete entry in its own autocomplete list to address the item. Open a new message, start addressing to the user in question. When the user's name appears in the autocomplete list, arrow down to it and press Delete. Now re-address the message as normal, and Outlook will resolve with the GAL instead of the local autocomplete.

The problem was that LazyFolk explain. But to solve it, i do a backup to PST of the mailbox, then disable-mailbox. Then, i run enable-mailbox & import PST. All is OK.

My problem was that after the AD user deletion, the Backup Team restore the full mailbox (so, they restore with all rules problem).

I tried to solve the rules problem with MCFMapi but I got an error message each time i tried to delete the bad rules.
