The Developer Justin was a great help.
Below is the communication we had…….

Sorry for the delay in response. Don’t know if you have figured it out yet, but it will be hard to help you with out more information.
My initial guess is that you are using the email address instead of the UPN. e.g. the users UPN is [email protected], but email is [email protected]
If you can send me a copy of the user CSV, screen shots of the General, and Account tabs, in Active Directory Users and Computers, what your impersonation account user is and the print out of this command: “Get-MailboxPermission -Identity [email protected] fl” I will be in a better position to help you.
One other trouble shooting tip, in a browser you should be able to go to the OWA site and impersonate the user:
http://webmail.domain.com/owa/[email protected]
then login with you MWI user: e.g. [email protected], it should open his mailbox.
