Clients do not connect to Microsoft Lync 2013 servers after installing Endpoint Protection 12.1.6 or 12.1.6 MP1
Last Updated August 10, 2015
Lync Server 2013 Front-End service cannot start after migrating to Symantec Endpoint Protection (SEP) 12.1.6 or 12.1.6 MP1.
The SEP installer installs code signing certificates during the install process. One of the certificates was installed into the Trusted Root Certification Authority store instead of the Intermediate Certification Authority store.
