In the past, I have always run exchange on my domain controller, which I know is not recommended, but never had any issues with it. Recently I decided to split them up and run 2 servers (vmware) They are both Windows Server 2012 R2 Datacenter. The first server is called XXXPDC and the other is XXXMAIL. Domain name is XXX and company.com . First I built them both and ran all updates and activated them. Then I added the AD and DNS role to XXXPDC and then joined XXXMAIL to the domain. After a few reboots, then installed Exchange Server 2013 Ent on XXXMAIL. Everything appeared to go perfect, but I do not have the Tab that would normally say email address in each users properties. I can open ADUC from either server and they both have updated information. What do I need to do to get this fixed?
