This is a completely fresh Lync 2013 install on a test domain. There are only two servers on the domain currently, a domain controller and the Lync front end server.
I have the Front End server completely installed and the various clients connect without issue. However, they can't actually chat with each other at all because you can't find anyone when you type a name into the search. You only get this message:
"Address book synchronizing. Results may not be current."
I'm sure I am making some huge noob mistake right now. Do I have to have Exchange installed in order for Lync to work or should a domain controller and the Lync server be enough?
Thanks for any advice that anyone can give me.
