I am trying to work out an issue with NDR's after a mailbox migration cross forest. I have read most article here and this article too : http://therealshrimp.blogspot.com/2010/01/cross-forest-mailbox-migration.html#comment-form

Not sure what I am doing wrong but it seems like the system does not like the x500 that I am using

Here is our current setup:

domain a.com
Exch 2007

domain b.local - new forest with trust in place
exch 2010

Here are my steps:
Create test user in domain a - log in and send / receive some test messages  on 2007 system

run prepare move on the test user
Run ADMT on test user
New Move Request on test user

Log into new exch 2010 and setup mail contact for the 1 user I was emailing with on the old exch 2007 system with test user. I add a custom x500 address for that user based on the output of running "get-mailbox "user" | fl legacyExchangeDN on the 2007 system

log into new exchange and new forest with test user and reply to an old email from a user with a new mail contact with x500 address in 2010

I get this NDR:

IMCEAEX-_O=ORGNAME+20AND+20ORG_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=USER@domainb.local

not sure why it is putting the domain b .local at the end of the NDR

Tried SMTP instead of X500?

The mail contact in 2010 forest has both SMTP and x500 - smtp points to the correct external domainb.com (not .local)

Local address set as the primary maybe?

no the local address is not even listed - only addresses are the x500 and the external

My only other thought is that something got screwed up in your accepted domains in EMC.  Sorry for the lack of support on this one.

got this working by converting user to mail contact not mail user also "started" over again and migrated whole new users and used a new test user in old Exch 2007 domain - this worked fine
