Enabling screen sharing for participants in Zoom meetings

1. Open the Zoom desktop client.
2. Start or join a Zoom meeting as the host. 
3. On the controls toolbar, click the upward arrow icon next to Share Screen .
4. Click Advanced Sharing Options.
   A pop-up window will appear.
5. Under Who can share, select All Participants.
   All participants in the meeting will be able to share their screen in this session.

Notes:

• Changing this setting during a meeting only affects this current session. Restarting the meeting or starting a different meeting will revert the Screen Sharing options back to their default. To change the default for meetings you host, adjust the screen sharing settings on the Settings page on the web portal.
• You can also click Security from the controls toolbar and make sure that the Screen Share option is checked.
• If the options are greyed out, ensure that Multiple participants can share simultaneously is not selected in the Advanced Sharing Options window, as other options cannot be adjusted while it is enabled.
