I have a domain set up which is corp.domainname.com
When setting up email addresses it only allows user@corp.domainname.com. How do I make exchange use user@domainname.com instead of @corp.domainname.com? I still want the user to be able to log in the corp domain on their computer and use outlook with exchange.
1You can't. That isn't how domains work. – Ramhound – 2014-05-16T15:36:58.270
