I am trying to get Lync Mobile working internally only. We are running Lync Server 2013. I can get lync to work over our wireless on laptops just fine but when I try the mobile app on iOS or Andriod I cannot get it working. When looking into this solution it was suggested I run a reverse proxy with IIS ARR. I am confused on how to set this up and very new with lync and IIS settings. If anyone out there could help assist with setting this up that would be greatly appreciated.
