Hi, I set up a new Server with Exchange 2013 and a new DC server.
from a Windows 8 Computer all works fine: I can connect Outlook 2013 to Exchange
from a Windows 7 Computer only OWA works, Outlook with the common error: "...no Connection to Exchange server...
-> DNS is set up
-> Certificate is copied to all Computers (is a private one as this will be a small environment)
-> Outlook Anywhere is working
