How to Fix Repeated Microsoft Teams Errors by Clearing Cache

Product: Microsoft Teams
Device & OS: not provided
Scenario: Attempting to use Microsoft Teams but experiencing continuous or repeated application errors.
Observed behavior: Recurring errors in Microsoft Teams continue to appear despite restarting the app and logging back in.

Before you start

Ensure that you have completely closed Microsoft Teams before attempting to clear the cache. You can verify this by checking your system tray or task manager to confirm no Teams processes are running in the background.

Solution 1Recommended

Clear the Microsoft Teams Cache

Clearing the cache forces Teams to download fresh data, often resolving persistent errors caused by corrupted local files.

Damaged cache files are a common culprit for recurring errors, login loops, and synchronization issues in Microsoft Teams. Deleting these temporary files is safe and will not remove your chats or uploaded documents.

Quit Microsoft Teams entirely

Right-click the Teams icon in your system tray (Windows) or Dock (Mac) and select 'Quit'.

Locate the cache folder

On Windows, press Win+R, type '%appdata%\Microsoft\Teams', and press Enter. On macOS, open Finder, select Go > Go to Folder, and type '~/Library/Application Support/Microsoft/Teams'.

Delete cache files

Delete all files and folders inside the Teams directory to completely clear the corrupted cache.

Restart Microsoft Teams

Open Microsoft Teams again and sign in. The application will rebuild the necessary cache files automatically.

Official Microsoft Instructions: For OS-specific nuances or instructions tailored to the 'New Teams' app, refer to the official Microsoft documentation at learn.microsoft.com/microsoftteams/troubleshoot/teams-administration/clear-teams-cache.

Solution 2

Reinstall Microsoft Teams

If clearing the cache does not resolve the issue, reinstalling the application will replace any missing or severely damaged program files.

Frequently Asked Questions

Will clearing the Microsoft Teams cache delete my chats or files?

No, clearing the Teams cache will not delete your chat history, files, or contacts. All of this data is safely stored on Microsoft's cloud servers and will sync back to your device once you sign in again.

How often should I clear the Teams cache?

You only need to clear the cache when you experience performance issues, sync problems, or recurring error codes. It is not necessary as a routine maintenance task.

Why does Teams keep crashing even after reinstalling?

If Teams continues to crash after a reinstall, ensure your operating system is up to date, check for conflicting third-party software (like aggressive antivirus programs), or verify your network connection stability.
