Symptoms

We couldn't connect to the presentation because of network issues.
Additionally, the user cannot start audio or video in a meeting in Lync 2013.

Cause

This issue occurs because Lync 2013 does not use a configured HTTP proxy server to connect to the Edge infrastructure of the non-federated organization. Instead, Lync 2013 tries to directly connect to the Edge infrastructure incorrectly.
