What Causes the Microsoft Teams Welcome Screen Startup Loop? 🚨

The Microsoft Teams welcome screen startup loop often stems from corrupted cache, profile glitches, or outdated files. Here's a quick breakdown:

Symptom Common Cause Quick Indicator

Slow loading then loop Profile sync issues Stuck on "Setting things up" message
Loop after updates Outdated or conflicting versions New patches not applied fully

Recognize your issue? Jump straight to the fixes below. These are based on the latest Microsoft Teams updates, ensuring compatibility with current versions.

Step-by-Step Troubleshooting: Fix It in Under 10 Minutes 👆

Start with the simplest solutions—they fix most Teams startup loop problems. Perform these on Windows (most affected OS); macOS tweaks are similar but use App Data equivalents.

  1. Force-Quit and Restart Teams Properly
    Close Teams via Task Manager (Ctrl+Shift+Esc > Processes > End task on all Teams.exe). Relaunch from Start Menu. If it loops again, proceed.
  2. Clear Teams Cache (Most Effective Fix!)
    Quit Teams completely. Navigate to %appdata%\Microsoft\Teams in File Explorer (paste and hit Enter).
    Delete these folders: Cache, Blob_storage, Databases, GPUCache, IndexedDB, Local Storage, tmp.
    Restart Teams. This resolves 70% of welcome screen loops by wiping temporary glitches.
Step-by-step guide to clearing Microsoft Teams cache folders
  1. Reset Teams Settings
    In Teams, go to Settings > General > Reset to default theme (if accessible). Or, delete %appdata%\Microsoft\Teams\desktop-config.json and relaunch.
  2. Update or Reinstall Teams 🔄
    Check for updates via profile icon > Check for updates. If stuck, uninstall via Settings > Apps > Microsoft Teams > Uninstall.
    Download the latest from Microsoft's official site and reinstall. Avoid Microsoft Store version if issues persist—use direct MSI installer.
  3. Sign Out from All Devices
    On another device or web.teams.com, go to Settings > Devices > Sign out everywhere. This syncs your profile and breaks loops from multi-device conflicts.

Pro Tip: After each step, test Teams. Success? 🎉 You're done! Still looping? Dive deeper.

Advanced Fixes for Stubborn Microsoft Teams Loops 🛠️

If basics fail, target deeper issues:

  • Delete Teams Registry Keys (Windows Only—Backup First!)
    Run regedit. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\Teams and delete the Teams folder. Restart PC.
  • Check Antivirus Conflicts
    Temporarily disable real-time protection (e.g., Windows Defender). Add Teams to exclusions if it helps.
  • Create New User Profile
    Windows: Settings > Accounts > Family & other users > Add account. Test Teams there—migrate data if it works.
