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 :

Serveur de génération :
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

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 ?
