We're using Skype for Business and it's a daily source of issues. Call quality is often terrible and - unrelated to the audio/video aubject - screen sharing is so laggy that it is literally unusable most of the time ("Please click over there. wait for visual update "Now do..").
Another fun issue is that you cannot directly paste stuff without starting a conversation. It will block your message as "too long" most if the time, unless you write something meaningless and short first. "Hey. Skype sucks. Incoming error I need your help with:".
