Problem
Microsoft Teams screen sharing does not work during a meeting. The Share button may be missing, the screen selection window may not appear, or other people may only see a black screen. In some cases, you can share a window but not your full screen, or screen sharing works on one device but not another.
This is usually caused by app permissions, browser limitations, organisation meeting policies, graphics issues, outdated Teams versions, or another app interfering with screen capture.
Solution
Check that you are allowed to share in the meeting, confirm Teams has screen recording permissions, update the app, and try sharing a specific window instead of the full screen. If the desktop app fails, test screen sharing using Teams on the web at https://teams.microsoft.com.
Step by step instructions
Check whether sharing is allowed in the meeting
Some meetings restrict who can present or share content.
In the meeting, look for the Share button.
If the Share button is missing or disabled, you may not have presenter permissions.
The organiser may need to change your role from attendee to presenter.
Ask the organiser to check meeting options if you cannot share.
Try sharing a window instead of the full screen
Full screen sharing can fail if Teams cannot capture the whole display.
In the meeting, select Share.
Choose a specific window, such as:
- PowerPoint
- Word
- Excel
- Browser window
- Application window
If window sharing works but full screen sharing does not, the issue is likely related to display permissions or graphics capture.
Restart Teams before the meeting
Close Teams completely.
On Windows, right click the Teams icon in the taskbar or system tray and select Quit.
On macOS, quit Teams fully from the dock or menu bar.
Reopen Teams and rejoin the meeting.
Test screen sharing again.
Check screen recording permissions on macOS
macOS requires screen recording permission before Teams can share your screen.
Open System Settings.
Go to Privacy and Security.
Select Screen Recording.
Make sure Microsoft Teams is allowed.
If you change this setting, quit Teams completely and reopen it.
Without this permission, other people may see a blank screen or Teams may be unable to share.
Check browser permissions for Teams web
If you use Teams in a browser, open:
Join the meeting and select Share.
Your browser may ask for permission to share a tab, window, or screen.
Allow the request when prompted.
If sharing fails in one browser, try another supported browser.
Update Microsoft Teams
An outdated Teams app can cause sharing and rendering problems.
Open Teams.
Select Settings and more near your profile picture.
Choose Check for updates if available.
Restart Teams after updating.
If Teams is badly broken, reinstall it from:
Check display and graphics issues
Screen sharing can fail if there is a graphics driver issue or unusual display setup.
Try these checks:
- Disconnect extra monitors temporarily
- Turn off remote desktop or virtual display tools
- Restart your computer
- Update graphics drivers
- Avoid switching display settings during the meeting
After making changes, rejoin the Teams meeting and test sharing again.
Close apps that may interfere with screen capture
Some apps can interfere with screen sharing or overlay on top of shared content.
Close unnecessary apps such as:
- Screen recorders
- Remote access tools
- Video meeting apps
- Graphics overlay tools
- Game capture tools
- Virtual camera apps
Then restart Teams and try sharing again.
Check organisation screen sharing policies
For work or school accounts, your organisation may restrict screen sharing.
Ask your IT administrator to check whether:
- Screen sharing is enabled for users
- External users are allowed to share
- Meeting policies restrict presenter permissions
- Guest users are blocked from sharing
- App protection or security tools are limiting screen capture
Optional methods or tools
- Try Teams on the web at https://teams.microsoft.com
- Share a single application window instead of the full screen
- Upload a PowerPoint file and present it directly in Teams
- Restart your computer before important presentations
- Ask the organiser to make you a presenter if sharing is disabled
Best practices or tips
- Test screen sharing before important meetings
- Close private or sensitive windows before sharing
- Share a window instead of your full screen when possible
- Keep Teams and graphics drivers updated
- Check macOS screen recording permissions after system updates
Microsoft Teams screen sharing problems are often caused by permissions or meeting role restrictions rather than a broken meeting. If the Share button is missing, the organiser may need to grant presenter permissions before you can share.
If screen sharing shows a black screen or does not start, check app permissions, update Teams, and try sharing a specific window instead of the whole desktop. For browser users, https://teams.microsoft.com can also help confirm whether the problem is with the installed desktop app.
