Assume that Domain Name System (DNS)-based automatic discovery is the only automatic discovery method that is deployed in a Microsoft Lync Server 2013 environment. In this situation, Lync 2013 clients do not discover the Exchange Web Service (EWS) servers.
To work around this issue, use one of the following methods:
- Deploy Http-based automatic discovery in the environment.
Note The URL of the Http-based automatic discovery must be case sensitive.
- Use a Lync 2010 client instead of a Lync 2013 client.
