Resetting the app clears its local cache and corrupted data without deleting your messages, which frequently resolves freezing issues.

Click on 'Apps' in the left-hand menu, then select 'Installed apps' to view all the programs installed on your computer.
Scroll down or use the search bar to locate 'Microsoft Teams'. Click the three dots (More options) next to the app and choose 'Advanced options'.

Frequently Asked Questions
Why does my Microsoft Teams keep freezing on Windows?
Teams usually freezes due to corrupted local cache files, outdated application versions, high system resource usage, or conflicting background processes on your Windows computer.
Will resetting Microsoft Teams delete my messages or files?
No, resetting the Teams desktop app only clears local app data, sign-in details, and cache. Your messages, channels, and files are safely stored on Microsoft's cloud servers and will reappear once you log back in.
What should I do if resetting the app doesn't fix the freezing issue?
If resetting doesn't work, try completely uninstalling Microsoft Teams from the 'Installed apps' menu, rebooting your computer, and downloading the latest version from the official Microsoft Teams website.

Yes, you can temporarily bypass desktop app issues by logging into the Microsoft Teams web app (teams.microsoft.com) using a supported browser like Microsoft Edge or Google Chrome.
