Exchange LDAP Constraint Violation while using forwarding tab

Hi all,

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.

Regards

Are these two separate Exchange orgs?
If so, then you cannot use accounts from one domain to forward to another domain. You can only forward to objects in the same Exchange org - user accounts, contacts, lists etc.

You have two options.

1. Contacts
2. Remove the account from the old domain and then configure the old Exchange server so that it is not responsible for all email for that domain and the email will go across. That does mean that users who have been moved will not appear in the GAL of the old domain, nor will they be able to part of any distribution lists (although that can be worked around).

Yes these are two separate Exchange oragnization.

So i may use the Exchange Migration Wizard tool to move my user to my brand new exchange server right?

That is one way of doing it.
You could also look at the migration tools from people like Quest. They may have something that makes it easier for you to manage.
