Fix Teams Microphone Does Not Work in Microsoft Edge

When you join a Teams call in Microsoft Edge, the microphone may stay silent even though it works in other apps. This problem usually comes from browser permissions, privacy settings, or a corrupted audio device cache. This article explains why Edge blocks the mic and walks you through the exact fixes that restore your audio input.

You will learn how to check Edge site permissions, clear the browser cache, reset Teams call settings, and verify Windows microphone privacy options. Each fix is tested on Windows 11 and Windows 10. Follow the steps in order, and test your microphone after each one.

Why Edge Blocks the Microphone in Teams

Microsoft Edge uses a permission system that controls which websites can access your microphone. When you first join a Teams meeting, Edge shows a prompt asking for permission. If you clicked Block or ignored the prompt, Edge remembers that choice and silently denies future access. The microphone icon appears crossed out in the address bar.

Another common cause is the Windows privacy setting that prevents desktop apps from using the microphone. Teams in Edge runs as a web app, but it still relies on the Windows audio stack. If the global microphone access is off, Edge cannot capture any sound even when the site permission is set to Allow.

A corrupted browser cache can also break the microphone. Edge stores temporary files, including audio device information. When these files become outdated or damaged, Teams may show a microphone that appears to work but sends no audio. Clearing the cache forces Edge to reload the device list.

Finally, Teams has its own device settings that can override the browser. If the wrong microphone is selected or the device is muted inside Teams, the call will be silent. These settings are stored per user profile, so they can be reset without affecting other apps.

Steps to Fix the Microphone in Teams on Edge

Follow these steps in order. Test your microphone after each step by joining a test call. Use the Teams test call feature by selecting your profile picture and choosing Settings > Devices > Make a test call.

Step 1: Allow Microphone Access in Edge

1. Open Edge and go to Teams
   Launch Microsoft Edge and sign in to Teams at teams.microsoft.com.
2. Click the lock icon in the address bar
   It is located on the left side of the URL. A dropdown menu appears.
3. Select Site permissions
   This opens the permission panel for the Teams site.
4. Find the Microphone row
   It shows either Allow or Block. Click the dropdown arrow next to it.
5. Choose Allow
   Select Allow from the list. Edge refreshes the page automatically.
6. Reload Teams
   Press F5 to refresh the page. The browser will now ask for microphone permission the next time you join a call.

Step 2: Enable Windows Microphone Access

1. Open Windows Settings
   Press the Windows key and type Settings. Click the Settings app.
2. Go to Privacy & security
   In Windows 11, select Privacy & security from the left menu. In Windows 10, select Privacy.
3. Click Microphone
   This opens the microphone privacy page.
4. Turn on Microphone access
   Toggle the switch so it reads On. This allows apps to use the microphone.
5. Enable Let apps access your microphone
   Turn this switch to On as well.
6. Check the desktop apps list
   Scroll down and make sure Microsoft Edge is listed and its toggle is On. If Edge is missing, restart the browser.

Step 3: Clear the Edge Cache and Site Data

1. Open Edge Settings
   Click the three-dot menu in the top-right corner of Edge and choose Settings.
2. Go to Privacy, search, and services
   Select this option from the left sidebar.
3. Click Choose what to clear
   Under Clear browsing data, click the button labeled Choose what to clear.
4. Select Cached images and files
   Check the box next to Cached images and files. Also check Cookies and other site data.
5. Click Clear now
   Edge removes the cached data. This does not sign you out of Teams, but you may need to sign in again.
6. Restart Edge
   Close Edge completely and reopen it. Then go back to Teams and test the microphone.

Step 4: Reset Teams Device Settings

1. Open Teams settings
   In Teams, click your profile picture at the top right and choose Settings.
2. Select Devices
   Click Devices from the left menu.
3. Check the Microphone dropdown
   Make sure the correct microphone is selected. If you have multiple audio devices, choose the one that works in other apps.
4. Click Make a test call
   This opens a test call window. Follow the prompts to record and play back your voice.
5. Reset the default device
   If the test fails, select Default from the dropdown. Teams will use the Windows default microphone.

If Teams Still Has Microphone Issues in Edge

Teams Shows the Microphone as Muted

The microphone icon in the meeting control bar may appear with a slash through it. This means the mic is muted inside Teams. Click the microphone icon to unmute. Also check the keyboard shortcut Ctrl+Shift+M, which toggles mute. If the icon still shows muted, your administrator may have set a policy that disables the microphone.

Edge Shows a Permission Error

If the address bar shows a crossed-out microphone icon even after you set Allow, the browser profile may be corrupted. Create a new Edge profile by clicking the profile icon and choosing Add profile. Sign in to Teams with the new profile and test the microphone. If it works, move your bookmarks and passwords to the new profile.

Windows Shows No Microphone Installed

Open Device Manager by right-clicking the Start button and selecting Device Manager. Expand Audio inputs and outputs. If your microphone is missing or has a yellow warning icon, update the driver. Right-click the device and choose Update driver. Then restart your computer and try Teams again.
