Teams just started using near 100% CPU and memory
Teams has recently begun consuming all available resources, resulting in a very sluggish user experience. Total CPU and memory usage are at or near100%, with Teams using about 80% of CPU and 23 GB memory.
I'm working on a Surface Book 3 i7 32 GB with everything up to date. Environment is Windows 11 and MS 365 GCC with latest Teams version 1.6.00.12455 (64-bit), updated 6/7/2023. The problems started in the last several days. Prior to that I'd been using Teams without notable incidents for years, about 12 months in GCC.
When I kill all Teams processes with Task Manager, resource usage levels immediately drop to normal (CPU about 30%). If I configure start-up without Teams and reboot, resource usage is also normal. I've run DISM.exe /Online /Cleanup-image /Restorehealth and sfc /scannow with clean results.

Hi KenStewart2750 ,
It seems that you have already taken some appropriate steps to troubleshoot the high resource usage issue with Microsoft Teams. Since killing the Teams processes and configuring startup without Teams result in normal resource usage, it suggests that the problem lies within the Teams application itself. Here are a few additional steps you can try to resolve the issue:
1. Clear Teams cache: Sometimes, corrupted cache files can cause performance issues. To clear the Teams cache, follow these steps:
a. Close Teams completely (ensure it's not running in the background).
b. Press Windows Key + R to open the Run dialog box, then enter "%appdata%\Microsoft\Teams".
c. Delete all the files and folders within the Teams folder, except for the "Downloads" and "Logs" folders.
d. Relaunch Teams and check if the performance has improved.2. Update Microsoft Teams: Although you mentioned that you have the latest Teams version, it's worth verifying if any updates are available. To update Teams, follow these steps:
a. Open Teams and click on your profile picture in the top-right corner.
b. Select "Check for updates" from the menu.
c. If any updates are available, let Teams install them and then restart the application.3. Disable unnecessary features and add-ons: Teams has several features and add-ons that might consume additional resources. Disabling certain features can potentially improve performance. To disable features:
a. Click on your profile picture in the top-right corner of Teams.
b. Select "Settings" from the dropdown menu.
c. In the Settings window, navigate to the "Permissions" section.
d. Review the permissions granted to different applications and disable any unnecessary integrations.4. Run Teams in safe mode: Safe mode starts Teams with minimal features and add-ons. To launch Teams in safe mode, follow these steps:
a. Close Teams completely.
b. Press Windows Key + R to open the Run dialog box, then enter "teams.exe --safe".
c. Teams will start in safe mode, and you can check if the performance improves. If it does, it indicates that a third-party integration or add-on is causing the issue.Remember to keep your operating system, drivers, and Microsoft 365 applications up to date, as updates often include bug fixes and performance improvements that could address the issue.

KenStewart2750A windows update this week has fixed the issue. I have no headset, speakers or mic attached. This was just the idle program chewing up all resources. Clearly MS messed up another update, didn't tell anyone and took months to fix it.
I'm having the same issue and none of the suggested fixes has helped. Teams just grinds my system to a slow pondering mess. KenStewart2750
- Having the exact same problem, teams immediately maxes out on CPU usage and starts using up to around 16gigs of memory. Tried clearing the cache, completely uninstalling/reinstalling teams. with no results.

Can you provide the same instructions for Teams for Mac?
"Delete all folders except downloads and logs" - I see logs, but not downloads. Is there another file I should not delete?
- Teams has this problem on my PC for the last couple of months, none of the above steps remedy the issue. It used to work fine, now it just sits there consuming all available CPU cycles for no reason. I can't believe this program has been implemented by the worlds largest software producer, this is garbage.
