Hi,
I have an AD Domain with name "domain.lan" hosted in Windows AD server 2012. I need to install Exchange 2013 without changing the domain name(To avoid the major impacts in the infrastructure) ,at the same time, I want my users to send and receive mails , login by the domain name : "@domain.com", For Example, user@domain.com. I came to know that I can add an UPN and apply an email address policy that makes my work simple. I would like to understand is this a correct approach and supported my Microsoft ? Will there be any other issues in future ? Anyone is using this option??
Thanks in advance !!
