I'm currently having a big issue when i try to forward mail from a User member of domain A to a user member of domain B.
I'm always getting an LDAP constraint violation error.
Trust relationship between these 2 domains are ok and working.
I'm using Exchange 2k3 SP2 in both domain.
I must use this forwarding process to migrate all my Domain A user to my brand new domain B.
I already saw a similar topic, where someone saids that you must use contact forwading to do that, but i'm pretty sure that there is another solution.
I have over 1000 users to migrate and i don't want to create a contact for each of them.
Any help would be appreciate.
