When screen sharing people see black screen
- May 20, 2021Hi Viren_Manek; Believe is ISP related. Change the QoS setting in Teams fixed the problems for us. Your tenant admin needs to change this: Teams Admin> Meetings > Meeting Settings > Network Turn off -> Insert Quality of Service (QoS) markers for real-time media traffic Also update Teams client to the latest version. Log-out and log back in. Restart your Teams app. You may need to wait for the change to kick in. Good luck. Regards Tenny 
Hello Viren_Manek Do any of these help?
How to Fix Microsoft Teams Black Screen Issues - Technipages
Hi ThereseSolimeno,
I have tried the first 2 options but not the third one. Will try that.
In meanwhile, I found that when I use teams via web browser there are no issues and works fine. So, the issues is more likely with the installed app.
Thanks and Regards,
Viren
- ThereseSolimenoMar 29, 2021Former EmployeeYes that often happens. The tech support team is trained to ask whether the issue shows up on the web as well as the app.- Viren_ManekMar 29, 2021Brass ContributorOne question, I remember checking on the 1st link you provided before and it says that login to "Admin Centre". When I tried that link, it says that I do not have access....
 How can I get further on that solution?
