Hi laura_laura,
What is your environment, on-premises or online?
Does this issue persist all the time? Or
what do you do before this issue happened?
Does anyone else have the same problem?
Does this issue occur when you share between Windows and Mac, Mac to Mac or Mac to Windows?
While in a peer-to-peer session between a Windows Skype for Business client and a Mac Skype for Business client, and sharing is started by the Mac
Skype for Business client, the Windows Skype for Business client will not be able to see the Mac user's desktop. We have
a known issue.
If it isn’t the scenario, please provide us the error message if it has.
Best Regards,
Sharon Zhao
