Step-by-Step Fixes for Microsoft Teams "Something Went Wrong" Startup
1. Clear Teams Cache β The #1 Fix (Works 80% of Time!)
Cache corruption is the top villain. Here's how to wipe it clean:
| Platform |
Steps |
| Windows |
- Quit Teams fully (Task Manager > End all Teams processes).

%appdata%\Microsoft\Teams, hit Enter.

Cache, blob_storage, databases, gpuCache, IndexedDB, Local Storage, tmp.

| macOS |
- Quit Teams (Cmd+Q).
- Open Finder > Go > Go to Folder, enter
~/Library/Application Support/Microsoft/Teams.
- Delete same folders as above.
- Restart app.

Pro Tip: Do this weekly for peak performance. If cache is massive, it's likely the issue!
2. Reset Microsoft Teams Settings
For stubborn cases:
- Open Settings app (Windows) or System Preferences (Mac).
- Search "Apps" (Win) or "Applications" (Mac) > Find Teams > Advanced > Reset.
- Confirm β this clears settings without deleting data.
- Relaunch. Your accounts stay intact!
3. Update or Reinstall Teams
Outdated versions cause crashes. Check for updates:
- In Teams: Profile > Check for updates.
- Or download latest from official site.
Still no? Uninstall via Settings > Apps, then reinstall. Fresh install fixes corrupted files 100%.
4. Run as Administrator & Disable Antivirus Temporarily
Permissions matter:
- Right-click Teams icon > Run as administrator (Windows).
- Pause antivirus (e.g., Windows Defender, Norton) for 5 mins, test launch.
- Add Teams to exclusions if it works.
Bonus for enterprises: Toggle off proxy in Teams Settings > Devices > Make a test call (reveals network tweaks).

For power users:
