When I would select Help –> Give Feedback in Lync 2013 – both Beta and Release as shown below:
I would get this error message:
“Cannot perform the action because the related web page was not available from your Internet browser. If you have not selected a default web browser, please specify one in the Control Panel. Otherwise, if the problem continues, please contact your support team.” (spelling out the message here so search engines can find it.)
Curtis provided a link for me in this post. I’m putting it here so I have easy access. Thanks Curtis!
