Bottom Line: It is 100% safe to delete the Microsoft Teams cache. Clearing it will not delete your Teams channels, chat history, or shared files. It is the official Microsoft troubleshooting step for fixing Teams performance slowdowns and sign-in loops.
What is the Microsoft Teams Cache Folder?
Located at %AppData%\Microsoft\Teams (or %LocalAppData%\Packages\MSTeams_8wekyb3d8bbwe for New Teams) on Windows, and ~/Library/Application Support/Microsoft/Teams on macOS, this folder holds cached data for the Teams app.
Microsoft Teams caches:
- Meeting & Call Data: Meeting logs, background images, and video stream caches.
- Shared Attachments: Pre-rendered image and document thumbnails from team chats.
- Web App Runtime Cache: Electron / WebView2 web storage.
Over months of remote work, Teams cache continuously expands to 3 GB to 10 GB, slowing down app launch times.
