I have successfully migrated a User and Computer account using ADMT. The user is able to login to the computer with the new account and is able to open outlook receive mail but is not able to send internal or external mail. The Exchange server is still in the Old domain. The bounce back message received was that the user doesn't have permissions to send to the recipient. When I migrated the user I did migrate the SID history so why is mail not being about to be sent? The body of the bounce back message is as follows:
