Hello,
i got the problem that I can not use ews with Lync. Main issue is that it can not find the url for ews. First I thought its an authorization issue but I could authenticate against autodiscover service. At the moment is just plain and simple. The autodiscover service just gives back no settings and, therefore, the client can not use them.
Here is a simple Trace of an AutoDiscoverRequest for an existing user (administrator@contoso.com). I can access this user via owa. My Exchange is 2013-exchange.contoso.com.

As you can see. The Autodiscover just does not respond with any settings for the user. I checked several times and all the internal and external urls for the ews, ecp etc. are set and fine. DNS Records for Autodiscover are good, because the client sends
the request. Certificates are also not possible because I get a "good" answer.
Any ideas?
