Hi Passkeycs,
I would like to confirm if you want to share desktop in Mac with Windows and set screen refresh via remote connect. Based on my experience, this might be related to the network environment. Lync Online is a cloud product, and the connectivity may be affected by the end of network condition. So, you may do this in different places to get the expected results. As for “how to get around the 60 second screen refreshes from Mac to Windows using Lync screen sharing. ”Issue, to get better support, we have a group dedicated to dealing with Lync client issues, I recommend you post the question to the Lync forum. This will help us solve the question more quickly.
