Symptoms & Diagnosis
Microsoft Teams usually updates automatically in the background. However, various system conflicts can interrupt this process. You might notice the “Update failed” banner at the top of your app window or find that certain new features are missing despite your colleagues having them.
Common symptoms include the application getting stuck in a “Checking for updates” loop or displaying error codes like 0x80040154. If your Teams version is significantly outdated, you may also experience connectivity drops or calendar sync issues.
To diagnose the issue, check your current version. Click the three dots (…) next to your profile picture, select “About,” and then click “Version.” If the date listed is more than a month old, your automatic update mechanism is likely compromised.

Troubleshooting Guide
If the automatic process fails, you can force the application to refresh its files. The following table highlights common update roadblocks and their primary causes:
| Error Type | Common Cause | Primary Fix |
|---|---|---|
| Update Failed Banner | Network interruption | Manual Refresh |
| Infinite Loading Loop | Corrupt Cache Files | Clear Cache Folder |
| Permission Denied | Lack of Admin Rights | Run as Administrator |
Method 1: Force Update via the UI
The simplest way to trigger a manual check is within the app. Click on the “Settings and more” (three dots) icon in the top right corner. Select “Check for updates.” Teams will look for updates in the background while you continue to work.
Method 2: Clearing the Teams Cache
Often, a manual update fails because the local cache is corrupted. You can clear this using the command line to reset the update environment. Close Teams completely before running this.
# For Windows Users: Clear Teams Cache via CMD
rmdir /s /q %AppData%\Microsoft\Teams
Method 3: Manual Reinstall
If the app refuses to update through the interface, the most reliable manual method is a “dirty install.” This involves downloading the latest executable from the official Microsoft website and running it over your existing installation. This replaces system files without deleting your chat history.
Prevention
To prevent future update failures, ensure that Microsoft Teams has permission to run in the background. Check your firewall settings to make sure that the Teams update URLs are not blocked by your organization’s security policy.
Keep at least 5GB of free space on your system drive. Teams downloads update packages in the background, and insufficient disk space is a leading cause of silent update failures. Regularly restarting your computer also clears temporary files that might lock the update service.
Finally, avoid using third-party “app cleaners” that might accidentally delete the Teams Update.exe file located in your AppData folder. If you are on a managed work device, contact your IT department to ensure they haven’t disabled user-initiated updates via Group Policy.
