Question

Screen sharing works for a few minutes then drops during meetings

Z33 0

I am currently using Teams on Mac, 1.4 GHz Quad-Core Intel Core i5, Mac OS 15.5 (24F74). Microsoft Teams version 25212.2404.3875.1360.

I can initiate screensharing but after a few minutes, it automatically stops sharing, takes me back to the teams meeting screen. The duration of the screen sharing varies. Sometimes its 5 minutes, sometimes lesss. There seems to be no trend to this. It stops sharing when I am scrolling/interacting with items on the screen or even when I am not. Absolutely no trend in when it happens.

I have tried deleting Teams, restarting the computer then re-installing. I have tried checking Teams and my Mac for updates... nothing. This has been going on for about 2 months now

Dear @Z33,

I hope you're having a nice day. Thank you for reaching out to the Microsoft Q&A forum and for sharing your concerns.

I understand how inconvenient it must be to experience screen sharing interruptions during Teams meetings on your Mac.

Based on your description, the issue may stem from network instability, limited hardware resources, or performance challenges with the Teams client itself. There are a few steps you can try that may help improve the experience:

1/ You can start by checking your network conditions. Screen sharing in Teams is sensitive to fluctuations in connectivity.

Microsoft recommends keeping:

Roundtrip time should be under 200 ms.
Packet loss should be below 2%.
Bandwidth for screen sharing should ideally support up to 1.5 Mbps.

You can monitor these metrics using the Call Health feature in Teams:

During a meeting, click More actions (•••) > Settings > Call health to view real-time data.

2/ Next, ensure your Mac meets the performance requirements for Teams. Screen sharing can be resource-intensive, especially on older devices. If your Mac is under heavy load or running background applications, Teams may throttle or drop the session:

Close unnecessary apps during meetings.
Ensure your Mac is not overheating or running background tasks that consume resources.

3/ If you're using a VPN or third-party security software, consider disabling it temporarily to see if it affects screen sharing stability. These tools can sometimes interfere with real-time communication features in Teams.

4/ Lastly, you can try using the web version of Teams by signing in at Microsoft Teams

This can serve as a workaround, especially if the desktop client continues to experience issues.

Thank you for your reply. The call itself isn’t dropping, it’s just the screen sharing that keeps disconnecting.

I have used Teams screen sharing across various wifis and it happens each time I try. My friends will be on the same wifi and the problem doesn’t occur for them.

Dear @Z33,

Thank you for your update and for sharing the details of your experience. I truly appreciate the time you've taken to describe the issue, and I sincerely apologize for the inconvenience this has caused.

Based on your description, it appears the issue may be specific to your device rather than the network itself. While others on the same Wi-Fi network are unaffected, your experience suggests that local factors such as outdated drivers, background applications, or system resource limitations may be interfering with Microsoft Teams’ screen sharing functionality.

It’s important to note that Teams relies heavily on your device’s hardware, particularly the CPU and GPU. If these components are underpowered or under strain, screen sharing may become unstable even with a strong network connection.

To help improve your screen sharing experience, I recommend the following steps:

Update your network and display drivers via Device Manager to ensure optimal compatibility.

Lower your screen resolution temporarily and test screen sharing to check for performance improvements.

Close unnecessary applications during Teams meetings to free up system resources.

Ensure your Mac is not overheating or running intensive background tasks that may affect CPU/GPU performance.

Clear the Teams cache by closing the app and deleting the folder located at %appdata%\Microsoft\Teams.

Temporarily disable antivirus or firewall software to rule out interference with Teams.

Try using Teams via a web browser at teams.microsoft.com to see if screen sharing behaves more reliably.

I understand this may not be the resolution you were hoping for, and I genuinely wish I could offer a more direct fix.
