Internal AD domain is ad.mydomain.com where external domain is mydomain.com.
Will be installing Exchange 2010 and need to make sure all users will be viewed as user@mydomain.com and not user@ad.mydomain.com.
We would want Outlook setup to see mydomain.com and we would want OWA login to use mydomain.com.
I have been searching for a clear answer, but apparently I am not searching the right terms to find the answer. I believe UPN is part of the solution, but I thought I read somewhere about some sort of rule setup involved in this.
Could someone point me in the correct direction on making this happen.
Thanks
