How can both internal and external email addresses have the same domain?
My company domain of firstname.lastname@example.org is different than my isp which is email@example.com. att isn’t going to allow my company use att.net and my company could not use mycompany.com if we were using the isp email address. Can you explain this a little more clearly? Perhaps this is why there is a problem.

Here the only solution i see at the moment is to rebuild the Exchange domains with somethin like <i>yourdomain.local </i>instead of the real <i>yourdomain.com</i> and then have the POP3 connector download the messages to the user’s mailboxes.
You can then set the default SMTP address to be <i>yourdomain.com</i> instead of <i>yourdomain.local</i>.
This is the final solution I found from Microsoft Support. I will test it as soon as possible but it’s exactly the problem I have:
