Bottom Line: It is 100% safe to clear the New Microsoft Teams app cache. Resetting Teams data will NOT delete your chat history, channel files, or scheduled Outlook meetings.
What is the New Microsoft Teams App Cache?
Located at %LocalAppData%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache on Windows 10/11, this folder is used by the New Microsoft Teams 2.0 (MSIX version).
Unlike classic Teams (%AppData%\Microsoft\Teams), New Teams is a WebView2 app that caches:
- Meeting Media Assets: Shared screen thumbnails, avatar icons, and background blur effects.
- WebView2 Cache: Local web app cache for chat channels, Planner apps, and OneDrive tabs.
Over months of video meetings and team chats, New Teams cache hoards 2 GB to 8 GB+ of drive space.
