    Hi 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

Hi,

 

Do people still have this problem in 2023?

 

I am experiencing exactly same issues in the last few months.

 

Even after reimagine my laptop, the problem is still there:

  • Sharing from web works perfectly 
  • Sharing from teams works sometimes, but sometimes the users see black screen and sometimes it freezes.

I changed ISP from Dodo to Superloop to fix the problem.

 

I suggest that you try connecting via various unrelated ISPs to troubleshoot. 

Cheers,

Daryl
