Yes

Explanation:
The Microsoft Lync Connectivity Analyzer tool has a very specific purpose. It is meant to determine if a Lync
environment, either on-prem or Skype for Business Online, meets the necessary requirements for clientconnectivity from mobile clients and the Lync Windows Store App.
The tool, in the course of its analysis, tests several components. Among them, it checks public DNS records to
make sure the necessary A records and SRV records are in place. It also checks the proxy configuration for the
environment. Lastly, but definitely not least important, it checks on the validity of the SSL certificates that are in
place.
