I have a lync 2013 environment setup along with a reverse proxy server for mobile users.
Desktop users can sign in fine using the 2013 client, however apple devices are unable to sign in unless they use the 2010 application.
Is this down to settings on the server or somethign that needs changing on the apple devices?
If i try to sign in using the 2013 application it states: ‘Cant connect to the server. It may be busy or unavailable. Please try again’
