4. Quick Fixes for the Microsoft Teams App in Google Chrome
There are a few common issues that cause Microsoft Teams to stop working in Google Chrome. Below, we’ll cover the solutions that people have reported got their Teams back up and running.
Update Google Chrome
Open Google Chrome.Click the three vertical dots in the top-right corner and select Help > About Google Chrome.
Chrome should automatically begin checking for updates. If not, click Update Google Chrome.
Once the updates are installed, select Relaunch.
Enable Third-Party Cookies
Disabling third-party cookies in Chrome prevents Microsoft Teams from loading properly. Try enabling third-party cookies for teams.microsoft.com to fix this issue.
Select Privacy and Security.
Scroll down to Sites that can always use cookies and select Add.
Add the following sites, making sure to select Including third-party cookies on this site:
[.]microsoft.com[.]microsoftonline.com[.]teams.skype.com[.]teams.microsoft.com[.]sfbassets.com[.]skypeforbusiness.com
Restart Chrome and see if Teams is now working.
Clear the Teams Cache on Google Chrome
Occasionally, the Chrome cache can cause all sorts of problems. To clear your cache:
Open Google Chrome.Click the three vertical dots, hover over History and select History.
Click Clear browsing data.
Make sure that Browsing history and Cached images and files are selected, and hit Clear data.
5. Wait for the process to complete and see if Teams is now working.
Note: Since the Teams web app operates via your browser, it doesn’t generate its own cache files. However, you can clear the Teams desktop app cache. Simply open File Explorer, enter %appdata%\Microsoft\Teams into the search bar and delete all items in that folder.
Disable Chrome Extensions
Likewise, extensions in Chrome sometimes interfere with its normal function. To see if any of your extensions are causing an issue, try disabling them all at once. If Teams now works, re-enable them one by one to find which one is at fault.
Open Google Chrome.Click the three vertical dots, hover over More Tools and select Extensions.
Toggle off every extension.
Reset Chrome Settings
The final fix to try is resetting Chrome to its default settings.
Open Google Chrome.Click the three vertical dots and select Settings.
From the left-hand menu, select Advanced > Reset and clean up.
Click Restore settings to their original defaults.
Select Reset settings.
Let the process complete, then sign in to your Microsoft Teams account and check if it’s now working. Quick Fixes for the Microsoft Teams App in Microsoft Edge
One of the common problems in Microsoft Edge that prevents users from loading Microsoft Teams is the “login loop” issue. Usually, this is caused by using the Trusted Sites security feature and not allowing access to Teams.
If you’re having this problem on a work or school computer, you may need to contact your IT administrator to do this step.
Open Microsoft Edge.Select the three horizontal dots at the top-right corner and then click Settings.
In the left-hand menu, select Cookies and site permissions.
Click Manage and delete cookies and site data.
Toggle on Allow sites to save and read cookie data.
Then, either toggle off Block third-party cookies or allow the following sites to save cookies on your device:[.]microsoft.com[.]microsoftonline.com[.]teams.skype.com[.]teams.microsoft.com[.]sfbassets.com[.]skypeforbusiness.com
To do so, scroll down to Allow and select Add. Repeat for each entry and ensure you select Include third-party cookies on this site.
If this doesn’t work, try the following fixes for Microsoft Edge:
Update Microsoft Edge
In Edge’s Settings, select About Microsoft Edge.
Edge should automatically update. Once it’s done, restart Edge and try Teams once again.
Clear the Application Cache on Edge
In Edge, click the three horizontal dots and select History.
In the pop-up, click the three horizontal dots and select Clear browsing data.
Ensure that Browsing history and Cached images and files are selected, and select Clear now.
Disable Edge Extensions

If so, enable the extensions one by one to see which is at fault.
Reset Microsoft Edge Settings
In Edge’s Settings, select Reset settings from the left-hand menu.
Select Restore settings to their default values.
Select Reset.
If none of these fixes work, the last thing to do is uninstall and reinstall Microsoft Edge.
6. Troubleshooting Antivirus Interference
Some users have reported that disabling their antivirus allowed their Teams web app to work again. Almost all reports of this type implicate Bitdefender Free as the culprit, and some reported that disabling Bitdefender, logging into Teams, and then re-enabling Bitdefender solved their issue for good.
To do so:
- Open Bitdefender.Select Settings under the Protection panel.Toggle off Bitdefender Shield and choose the appropriate length of time. Try to log in to the Microsoft Teams web app. If it works, re-enable Bitdefender to ensure your PC is safe from malware.
