Teams Cache Cleanup

Sometimes it is necessary to clear the Microsoft Teams cache to resolve issues such as:

• Teams not loading or stuck on a blank screen
• Missing messages, channels, or calendar/calendar entries
• Sign-in problems or authentication errors
• Outdated UI elements after updates

This script automates the process by closing Teams and Office apps, removing cache files, and restarting the apps. Both New Teams and Classic Teams are supported.

Clearing the Teams cache is nondestructive: it only removes temporary cache files. User data, including chats, files, and settings, will be preserved after clearing the cache.

Users will need to sign in to Teams again after the cleanup.

Features

• Detects and closes running Office apps and Teams.
• Clears Teams cache:
  • New Teams: %LOCALAPPDATA%\Packages\MSTeams_8wekyb3d8bbwe
  • Classic Teams: %APPDATA%\Microsoft\Teams
• Waits until Teams is fully closed before cleaning up.
• Restarts previously closed apps.
• Logs actions to %TEMP%\TeamsCleanup.log.
• Optional system restart prompt.

Usage

1. Download the latest release.

2. Double-click teams-cache-cleanup.bat to run.

3. Follow the prompts:

   • Save your work.
   • Confirm optional restart when prompted.

Notes

• This script removes the Teams cache completely but does not delete user data.
• Users will need to sign in again after cleanup.
• If Teams or Office apps fail to restart, check the log file for errors.
