You can migrate the user using ADMT. Or create a new mailbox, disconnect the existing one, and reconnect it to the new account.
When doing the last option, remember to add his Legacy Exchange DN (fount by AdsiEdit in the user account) as an X500 address after you connect the mailbox to his xxx.com account.

MoveTree can do exactly what you need, it will not effect the users mailbox.

It's old, but it still applies, I've used it successfully for this kind of move on Windows 2003 / Exchange 2003:

It has examples, but it doesn't have screen-shots if that what you mean? There's not a lot of point in having screen-shots in this case, it's a command line tool.

There are other articles on it, but they don't really offer any more content:

http://www.windowsitpro.com/article/domains2/jsi-tip-3219-using-the-movetree-utility-to-move-objects-between-domains-in-a-forest-.aspx

Your choices for this are limited to:

1. Use MoveTree
2. Use ADMT
3. Delete the existing user and create the user in the target domain
4. Do nothing

If I had to do it I would use MoveTree, as I said above, I've done so quite happily in the past.

Should the worst comes to the worst and it breaks the account you can simply default to option 3 and attach the dis-connected mailbox to the account.

Chris DentPowerShell DeveloperCommented:

It should connect. When did it say access denied? When you re-connect? Or when you attempt to access the mailbox?

Is the parent domain configured to run Exchange? Do you have rights to the account in the parent domain with the Exchange admin account you're using?

Did it successfully connect to the renamed account then? And if so, where does Access Denied come in?
