Exchange 5.5 Migration to 2003

I have a large migration project that involves migrating a NT 4.0 Domain with
Exchange 5.5 to a Windows 2003 Forest with Exchange 2003 that are in Native
Mode. There must be co-existance between the two during the migration and
the users that get migrated must keep the same smtp address. I have a test
environment and I am using ADMT to migrate objects over and perform security
translation, along with using the exchange migration tools to bring the
mailbox over. I also have ADC configured with two Inter-Org connections
configured as described in Microsoft Documentation. I think I am missing a
piece somewhere as I don't understand how mailflow occurs between users that
have been migrated over to the Exchange 2003 server. Once a user gets
migrated, the other users gets a bounce back when they try to email that
person. From reading, it should be using x.500 to deliver the email? Am I
trying to do something that's not supported?

Hi,

When you migrate a mailbox the ADC connection agreement should make sure
that the user is still visible in the 5.5 gal. The OU where the user is
configured in the connection agreement?

Check the user in the 5.5 gal and see that he looks correct.

What does the NDR say?
