Hi guys, I am currently on a single AD domain with an Exchange Server. Everything works fine. Supposedly there is a company merger and we want to create a separate AD domain with a separate Exchange server on the same network . My question is if user A wants to have an email account on the other new domain by connecting to the new Exchange server, can he do that on his Outlook by just adding a new account ? I will also create an account in the other domain. However his PC is joined to the 1st domain and not the new domain. Will he get prompted for a password every time he open Outlook? Preferably we wants to keep the servers separate.
