If you’ve tried to load up Microsoft Teams for a quick meeting and discovered the web app isn’t loading or working properly, you’re not alone.

We’ve researched the most common causes of Microsoft Teams not working so you don’t have to. In this guide, you’ll find 6 quick fixes that should get your Teams back up and running again in no time.

1. Try These Basic Fixes

The first thing to do if MS Teams isn’t loading is to try these basic fixes. If they don’t work, move on to the specific problems listed below. * Reboot your computer. 

• Check your internet connection.
• Disconnect and reconnect your webcam or microphone, and try connecting them through a different port. 
• Turn off any interfering programs such as Skype. To do so, open the system tray, right-click any potentially interfering programs and select Close.
• Check the Microsoft Office 365 official Twitter account or Microsoft Teams dedicated Twitter account to check if Microsoft Teams is currently experiencing downtime. 
• Check if your browser supports Microsoft Teams. Firefox, Safari, and Internet Explorer 11 do not support Teams. If you use one of these browsers, try switching to Google Chrome or Microsoft Edge, which are supported platforms. 

  2. Check Microphone and Webcam Permissions

  If your microphone or webcam isn’t working on the Teams application, try checking their permissions.

  1. Press the **Windows Key + I **to open Settings.
  2. Select Privacy.

3. Select **Camera**.

4. Toggle on **Allow apps to access your camera**.

5. Scroll down and ensure that **Allow desktop apps to access your camera **is also toggled on.

6. Repeat for **Microphone**.

Next, you’ll need to check that your web browser has allowed the use of your camera and microphone.

For Google Chrome:

1. Open Google Chrome.
   • Click the three vertical dots in the top-right corner and select Settings.

3. Select **Privacy and security **> **Site settings**.

4. Click **Camera**.

5. Ensure that the setting **Sites can ask to use your camera **is ticked.

6. Do the same for **Microphone**.

For Microsoft Edge:

1. Click the three horizontal dots and select Settings.

2. Select **Cookies and site permissions **and scroll down to **All permissions**.

3. Click **Camera**, and ensure that **Ask before accessing **is toggled on.

4. Do the same for **Microphone**.

**Note: **If your camera still isn’t working, check out our guide. 

3. Check Your Date and Time Settings

If you aren’t using the correct settings for your time and location, the Teams Web Client can have issues connecting you to their servers. 

1. Press the **Windows key + I **to open Settings.
   • Select Time & Language.

3. Make sure that **Set time automatically **and **Set timezone automatically** are toggled on.

4. Click **Restore settings to their original defaults**.

5. Select **Reset settings**.

6. 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.

1. Open Microsoft Edge.
   • Select the three horizontal dots at the top-right corner and then click Settings.

3. In the left-hand menu, select **Cookies and site permissions**.

4. Click **Manage and delete cookies and site data**.

5. Toggle on **Allow sites to save and read cookie data**.

6. 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

7. 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

1. In Edge’s Settings, select About Microsoft Edge.

2. Edge should automatically update. Once it’s done, restart Edge and try Teams once again.

Clear the Application Cache on Edge

1. In **Edge**, click the **three horizontal dots** and select **History**.

2. In the pop-up, click the **three horizontal dots** and select **Clear browsing data**.

3. Ensure that **Browsing history **and **Cached images and files** are selected, and select **Clear now**.

Disable Edge Extensions

1. In **Edge**, click the **three horizontal dots** and select **Extensions**.

2. In the pop-up, select **Manage Extensions**.

3. Toggle off each extension, then check to see whether Teams is now working.

4. If so, enable the extensions one by one to see which is at fault.

Reset Microsoft Edge Settings

1. In Edge’s** Settings**, select **Reset settings** from the left-hand menu.

2. Select **Restore settings to their default values**.

3. 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:

1. 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.
