Why can't I share my screen on Teams?

Screen Sharing may not be enabled in Teams if the admin has disabled the option or the application has not been granted the necessary permissions. Additionally, there may be other reasons why Screen Sharing is not working, such as:

  • An unstable internet connection
  • Conflicts with other apps
  • High display resolution
  • Outdated version of Teams
  • Hardware Acceleration enabled
  • Administrator configurations in Teams

Ask the meeting admin to allow everyone to present their screen

Firstly, ask the meeting admin if they've enabled everyone to present their screen during the meeting. If this option is disabled, no one in the meeting can share their screen. The admin can enable everyone to share their screen by following these steps:

  • Click on More at the top and select Meeting Options.
  • Expand the drop-down below Who can present? and select Everyone.
  • Click Save to save the changes and try sharing your screen.

Check your Internet connection

Next, check that the internet connection you're using is stable and fast enough to support screen sharing. Screen sharing requires higher bandwidth than usual. Perform a speed test to ensure that your internet connection is working correctly. If the speed is less than your plan, restart your modem and router.

Delete the app cache of Microsoft Teams

Microsoft Teams saves app and cache data to enhance the user experience. However, these cache files can become corrupted and cause Screen sharing issues. Delete the app cache data of Microsoft Teams by following these steps:

  • Press the Windows key + R key combination to open the Run dialogue box.
  • Type %appdata%\Microsoft\Teams and hit Enter.
  • The Teams folder will open. Press CTRL + A to select all the files and then SHIFT + DEL to permanently delete the cache files.
  • Restart the Teams app, rejoin the meeting, and try sharing your screen again.

  • Navigate to System > Display.
  • Click on the drop-down beside Display Resolution and select your desired resolution.

  • Open your web browser and navigate to the settings menu. This can usually be found by clicking the three dots or lines in the top right corner of the browser window.
  • Scroll down and click on "Settings" or "Preferences."
