In this guide, we'll walk you through how to clear Microsoft Teams cache on every device—Windows, Mac, web, and mobile. Follow these steps, and you'll be back to seamless collaboration in minutes! 🚀

Why Clear Microsoft Teams Cache? The Hidden Performance Killer

Your Microsoft Teams cache stores temporary files like images, chat history snippets, and app data to speed things up. But when it balloons with outdated junk, it causes:

• ❌ Slow loading and Teams lag
• ❌ Random crashes or sign-out loops
• ❌ High CPU/RAM usage
• ❌ Blurry avatars or missing emojis

Good news: Clearing Microsoft Teams cache flushes this bloat without deleting your chats or files (they sync from the cloud). Microsoft recommends it as a first-line fix for performance issues. ⭐ Pro tip: Do this weekly for peak performance!

How to Clear Microsoft Teams Cache on Windows (Quickest Method)

Windows users, this is your go-to fix for the desktop app. Takes under 2 minutes! ➡️

1. Quit Teams completely: Right-click the Teams icon in the system tray (bottom-right) and select Quit. Check Task Manager (Ctrl+Shift+Esc) to ensure no "Teams.exe" processes linger—end them if needed.
2. Open Run dialog: Press Win + R, type %appdata%\Microsoft\Teams, and hit Enter.
3. Delete cache folders: You'll see folders like Cache, blob_storage, databases, GPUCache, IndexedDB, Local Storage, tmp, and Code Cache. Select all (Ctrl+A) and delete. Skip meeting-addin, media-stack, or logs unless issues persist.
4. Restart Teams: Launch it—sign in if prompted. Boom! Smoother sailing. ✅

Bonus: For the new Teams (post-2023 redesign), also clear %localappdata%\Packages\MSTeams_xxxxx via Run if using the Store version.
