5 Ways to Fix Microsoft Teams Web Not Working

Quick Tips

• Microsoft Teams web app could fail to work due to incorrectly configured site permissions, a faulty extension, or server-related issues.
• Try checking your internet connection and restarting the browser to see if that helps.
• You can try clearing the existing browser cache if nothing else works.

Basic Fixes

• Sign out and sign back in: Authentication issues with your Microsoft account can sometimes cause Teams to stop working. You can try signing out of your account and signing back in.
• Check the Microsoft Teams service status: Teams servers may be experiencing problems. You can visit the Microsoft Office service status page to see if there’s a widespread outage.

Fix 1: Reset Site Permissions for Microsoft Teams

Misconfigured site permissions can also cause certain Teams features to stop working on your browser. For example, if you’ve accidentally disabled notification permissions for Teams, you won’t receive any alerts for new messages or calls.

To resolve such issues, reset site permissions for Microsoft Teams and configure them again. To do so, click the padlock icon on the left of the URL and click the Reset permissions button.

Fix 2: Correct System Date and Time

Is your computer set to an incorrect date or time? If so, apps and websites may be unable to connect to their servers. To avoid such problems, you can enable the automatic date and time feature in Windows.

Step 1: Press the Windows key + I to launch the Settings app. Click the Time & language tab and click on Date & time.

Step 2: Turn on the toggle for Set time automatically.

Fix 3: Disable Browser Extensions

Although third-party extensions bring additional functionality to your browser, not all are reliable. It’s possible that one of your browser extensions is acting up and preventing Teams from loading on your computer. To check this, disable all the extensions and enable them one by one.

Step 1: Type chrome://extensions (Chrome) or edge://extensions (Edge) in the address bar at the top and press Enter.

Step 2: Turn off the toggles next to the extensions to disable them.

After disabling all the extensions, restart the browser. If this gets Microsoft Teams to work, re-enable all extensions one by one to isolate the culprit and remove the problematic one from the browser.

Fix 4: Enable Website Cookies

Microsoft Teams web app may fail to work properly if you’ve blocked website cookies on your browser.

To enable cookies in Google Chrome: Type chrome://settings/cookies in the URL bar at the top and press Enter. Under General settings, select Allow all cookies.

If you use Microsoft Edge: Type edge://settings/content/cookies in the address bar and press Enter. Enable the toggle for Allow sites to save and read cookie data (recommended).

Fix 5: Clear Browser Cache

A corrupt or outdated cache can prevent your browser from loading websites. Hence, clearing browsing data whenever you encounter such issues is a good idea.

Step 1: To clear the browser cache in Chrome or Edge, press Ctrl + Shift + Delete on your keyboard to open the Clear browsing data panel.

Step 2: Select All time in the Time Range option. Mark the box that reads Cookies and other site data and Cached images and files.

Step 3: Now, hit Clear data.
