Cannot move certain mailboxes from one Exchange server to another

[systemsadmin3000]

I want to move some mailboxes from one server running Exchange 2003 SP1 to another server on the same site running Exchange 2003 SP2. We have three mailstores on the source server (General, Executives, Managers) and I have setup similar mailstores on the destination server. I set the a schedule to move the mailboxes. When I checked the following day some mailboxes were moved and other did not. When I tried to move the one that failed manually I got the following error:

<?xml version="1.0" encoding="unicode" ?>

Can anyone help on this?
