We have an otherwise functioning Lync 2013 server/client installation, but sharing out PowerPoints has resulted in a error "There was a problem verifying the certificate from the server. Please contact your support team" (see attached too). I have researched this here http://goo.gl/inDh9L
, which has not worked for me. I think I need to see the cert requirements for this operation, as everything else has been working for a while. Point me in the right direction?
