Fix Teams Screen Sharing Is Disabled in Microsoft Edge

When you try to share your screen during a Teams meeting, Edge may show a message that screen sharing is disabled. This usually happens because Edge blocks screen capture for security reasons or because a group policy restricts the feature. The problem can also appear if Edge is running in an incompatible mode or if the Teams web app lacks the proper permissions. This article explains why Edge disables screen sharing and walks you through the fixes that restore the Share Screen button.

Why Edge Disables Screen Sharing in Teams

Edge controls screen sharing through a feature called Screen Capture. This feature is part of the browser’s site permissions. When you grant screen capture permission to a site, Edge lets that site access your screen. If the permission is denied, Edge disables the Share Screen button in Teams.

There are three main reasons why Edge might block screen sharing:

Site Permission Settings

Edge stores a permission for each website that requests screen capture. If you previously clicked Block when Teams asked for permission, Edge will keep blocking it. You can change this in the site permissions settings.

Group Policy Restrictions

Organizations that manage Edge with Group Policy can set the Screen Capture Allowed policy. When this policy is set to Disabled, Edge blocks all screen sharing requests. This is common in companies that restrict data sharing for security reasons. The policy overrides any user permission settings.

Hardware Acceleration Conflicts

Edge uses hardware acceleration to render video and graphics. On some systems, this feature conflicts with the screen capture logic. The result is that the Share Screen button appears grayed out or the shared screen shows a black rectangle. Disabling hardware acceleration often resolves this.

Steps to Fix Screen Sharing in Teams on Edge

The fixes below work for Teams on the web and for the Teams desktop app when it uses Edge WebView. Start with the least invasive fix and work through the list.

Fix 1: Allow Screen Capture Permission in Edge

1. Open Edge Settings
   Click the three-dot menu in the top-right corner of Edge and select Settings.
2. Go to Site permissions
   In the left sidebar, choose Privacy, search, and services. Scroll down and click Site permissions.
3. Select Screen capture
   Under the Permissions section, click Screen capture. This opens a list of sites that have requested screen access.
4. Remove the Block for Teams
   Find the entry for teams.microsoft.com or your organization’s Teams URL. Click the trash icon next to it to delete the saved permission. This resets the permission to Ask.
5. Restart Edge and Teams
   Close all Edge windows and the Teams app. Reopen Teams and try to share your screen again. Edge will prompt you to allow screen capture. Click Allow.

Fix 2: Turn Off Hardware Acceleration in Edge

1. Open Edge Settings
   Click the three-dot menu and select Settings.
2. Go to System and performance
   In the left sidebar, click System and performance.
3. Disable hardware acceleration
   Toggle off the switch next to Use hardware acceleration when available.
4. Restart Edge
   Click Restart in the confirmation dialog that appears. Edge will close and reopen automatically.
5. Test screen sharing in Teams
   Open Teams, join a meeting, and click the Share Screen button. If the button is now active, the issue was related to hardware acceleration.

Fix 3: Enable Screen Capture Allowed via Group Policy

This fix applies only if your organization manages Edge with Group Policy. You need local administrator rights on your computer.

1. Open the Group Policy Editor
   Press Win + R, type gpedit.msc, and press Enter.
2. Navigate to the Edge policy folder
   Go to Computer Configuration > Administrative Templates > Microsoft Edge.
3. Find the Screen Capture Allowed policy
   Scroll down in the right pane and double-click Screen Capture Allowed.
4. Set the policy to Enabled
   Select Enabled, then click OK. This allows Edge to honor screen capture requests.
5. Update the policy
   Open a command prompt as administrator and run gpupdate /force. Then restart Edge and Teams.

Fix 4: Reset Edge Settings

If none of the above fixes work, resetting Edge to its default settings can clear any corrupted permissions or flags.

1. Open Edge Settings
   Click the three-dot menu and select Settings.
2. Go to Reset settings
   In the left sidebar, click Reset settings.
3. Choose Restore settings to their default values
   Click Restore settings to their default values. In the confirmation dialog, click Reset.
4. Restart Edge
   Close Edge and reopen it. You will need to sign in to Teams again and grant screen capture permission when prompted.

If Teams Still Has Issues After the Main Fix

Teams Shows a Black Screen When Sharing

A black screen during sharing usually points to a hardware acceleration problem. Turn off hardware acceleration in Edge as described in Fix 2. If that does not help, close other applications that overlay the screen, such as graphics drivers or screen recording tools.

Share Screen Button Is Grayed Out

A grayed-out button means Edge is blocking the screen capture permission entirely. Check the site permission for Teams in Edge Settings and ensure it is set to Allow. Also, verify that the Group Policy Screen Capture Allowed is not set to Disabled.

Team’s Web App Does Not Prompt for Permission

Sometimes Edge does not show the permission prompt. Clear the site data for Teams in Edge Settings > Site permissions > Screen capture. Then restart Edge and try again. If the prompt still does not appear, use the Teams desktop app instead of the web app.

Teams Desktop vs Teams on the Web: Screen Sharing Comparison

Item	Teams Desktop App	Teams on the Web (Edge)
Screen sharing support	Full support with system-level capture	Full support but depends on Edge permissions
Permission prompts	Uses Windows permissions, not browser prompts	Uses Edge site permissions and prompts
Group policy influence	Affected by Teams policies in the admin center	Affected by Edge policies and Teams policies
Hardware acceleration impact	Uses system graphics settings	Uses Edge hardware acceleration setting
Best for	Reliable sharing on managed devices	Quick access without installing an app

If you prefer the desktop app, you can download it from teams.microsoft.com/downloads. The desktop app avoids Edge-specific issues because it does not rely on browser permissions.

After applying the fixes, test screen sharing in a test meeting with yourself. Use the Share Screen button and select a single window or the full screen. If sharing works, the problem is resolved. For recurring issues, check the Teams admin center > Meeting policies to confirm that screen sharing is allowed for your users.
