Current Environment is:

Old domain ([strong]domain A[/strong]) two domain controllers, 1 Exchange 2003 sp2 server with about 90 users on.

New Domain is Parent domain ([strong]domain Z[/strong]) with exchange 2010 setup (HUB and CAS on one server, Mailbox on another server). Then two child domains where the users are setup ([strong]sol.domain.Z[/strong]) with trust setup when running DCPromo.

I’ve been doing a domain migration from Windows 2003 AD (domain A ‘old domain’) to a Windows 2008 AD (domain Z ‘new domain’). I have used ADMT for this and all users are on the new domain with correct NTFS permissions. No problem there (I don’t think).

Problem is trying to migrate the mailboxes over. I read that using ADMT first is not the best route but I have pushy managers. Enough said.

Exchange 2010 is installed on the parent domain and when I try to migrate a mailbox over using .prepare-moverequest I see green code ‘[strong]Appending x500....[/strong]’ with a [strong]warning ‘cannot  find corresponding object for .....[/strong]’ and ‘[strong]1 mailbox(s) ready to move.[/strong]’ I assume I can move on to the next step which is new-moverequest. This is the problem. When i run the command I get

[strong]‘The operation couldn't be performed because object 'test01@domain.z'[/strong] couldn't be found on 'domain Z'.’

Why can’t the user been seen? When I try setting up a new user mailbox on the exchange server I can see all the users on the child domain (sol.domain.z) and proceed to set up the mailbox and have tested and works.

Any help would be most appreciated and I am get to an end where to go from here.
