Hi guys,
I have a mac client that has newest version 14.0.10 of lync installed. The Mac works on OS X Yosemite
operating system. The problem is that when you connect to corporate LAN, lync never connects and gives
following error: Sign in to Microsoft Lync failed because the service is not available or you may not be connected to the Internet.
If you share a connection via mobile or connect via outside network, you are able to log in and lync functions properly
I have tried to update root certificate on mac via copying one from windows client, but with no luck.
