Hello.
I have three servers all running Windows Server 2012 in a domain called xyz.com. The 1st server is a domain controller, the 2nd server hosts Exchange Server 2013 mailbox role and the 3rd server hosts Exchange Server 2013 Client Access role. However, I would prefer my mailboxes to have a different namespace from the domain name. For instance, jsmith@xyz.co.uk and not jsmith@xyz.com.
What do I need to configure? Please help!
