It's already known that the MS Teams client causes sometimes performance issues. That's something that happens less often after any MS update. But, still, it happens and there are certain things that we can do to try to remedy it.
I have tried to summarize several points in a single post :)
MS Teams client crashes:
- Well, after the usual standard troubleshooting, ( check user license, check teams web app, perform an office repair... ), the first stepp will be clear the Teams client cache:
1. Fully quit Microsoft Teams and ensure it's not still running in background.
2. In Windows file explorer, navigate to %appdata%/Microsoft/Teams
3. Select everything in the folder and delete it.
4. Restart the MS Teams client. ( The necessary deleted content will be automatically recreated ).
- If it still fails, and the user is starting the software from the taskbar, try to run the .exe directly from the installation directory. If it works, just create a new shortcut from the .exe file.
- I have seen this kind of scenarios where we were able to fix this issue reinstalling Intel Graphic drivers.
MS Teams Slow Video Performance:
Slow video performance in huge meetings could be expected but, anyway, you could check your Network an see if some improvement is possible in your area.

On Microsoft Teams side, there are some tips in order to improve the meetings performance:
- Restart Teams.
- Close any applications or browser tabs that you aren't using.
- Disable GPU hardware acceleration in MS Teams.
To disable this function, select the "Settings - General" next to your profile picture at the top right of Teams, and then select the "Disable GPU hardware acceleration" option. You'll find it under "Application". ( A Teams client restart will be required ).
- Disconnect your monitor from the port replicator or docking station, and directly connect it to the video port on the laptop, if available.
- Empty Teams client cache. ( Steps explained in the previous point in this post ).
- Change the resolution of your 4K or UHD monitor, ( if it's the case ), to 1920 x 1080.
- Use DVI or HDMI instead USB-C to connect your monitor, if possible.
- Disable full screen mode in the meeting by selecting More actions > Full screen.
MS Teams App High CPU/Memory use:
Unfortunately there's no much to do as a high resources consumption by Microsoft Teams is expected, but anyway there're some tips to make the performance faster, already mentioned in previous points in this post, like:
- Restart Teams.
- Empty Teams client cache.
- Disable GPU hardware acceleration.
For sure, and for any issue, you have also the MS Teams logs, ( check the link below ). If you're thinking about to open a case with the MS support team, I'll suggest you to collect the logs reproducing the issue in order to speed up the resolutions, as probably that would be the first thing that the engineer will request to you.
