It would indicate that you have an @ in the users alias, alternatively any other special character that it doesn't like.

If you change the users alias in Exchange 2003 and try moving again

the problem is that the user doesn't have a UPN set, open AD users and computers -> find the user and open it > go to the account tab and you will notice that the UPN (Drop down list) is empty. use the drop down to select a UPN suffix it will fix it
