Step-by-Step Fixes: Banish the Microsoft Teams Welcome Error for Good

Start with the easiest – most users fix it in under 5 minutes. Follow sequentially for best results.

1️⃣ Clear Teams Cache (80% Success Rate!)

This wipes temporary files causing the loop. Super safe and fast.

Platform	Steps
Windows	Quit Teams completely (Task Manager → End all Teams tasks). Press Win+R, type `%appdata%\Microsoft\Teams`, hit Enter. Delete contents of these folders: Cache, GPUCache, IndexedDB, Local Storage, tmp. Restart Teams – welcome fixed! 🎉
macOS	Quit Teams (Cmd+Q). Open Finder → Go → ~/Library/Application Support/Microsoft/Teams. Delete: Cache, Code Cache, GPUCache, etc. Launch again.

2️⃣ Reset Microsoft Teams via Settings

If cache clear fails:

Open Windows Settings → Apps → Installed Apps → Microsoft Teams → Advanced Options.
Click Reset – this reinstalls core files without data loss.
Or macOS: Right-click Teams in Applications → Show Package Contents → Reset via Terminal: /Applications/Microsoft\ Teams.app/Contents/MacOS/Teams --reset.

Pro tip: Sign out from all devices first via web Teams. 🔑

3️⃣ Reinstall Teams Clean (Nuclear Option)

For stubborn loops:

Uninstall Teams (Control Panel → Programs on Windows; drag to Trash on Mac).
Delete leftover folders: %appdata%\Microsoft\Teams and %localappdata%\Microsoft\Teams.
Download fresh installer from Microsoft's official site.
Install and sign in – loop gone! 💥
