How do I share my screen during a Microsoft Teams meeting?

To share your screen during a Microsoft Teams meeting, follow these steps:

1. Join the meeting and click the 'Share' icon located in the control bar at the bottom of the screen.
2. Select the screen you want to share from the list of available options. You can choose to share your entire screen or just a specific window or application.
3. Click the 'Share' button to start sharing your screen with other meeting participants.
4. To stop sharing your screen, click the 'Stop sharing' button located in the control bar.

Note that if you're using a Mac, you'll need to give Teams permission to record your screen before you can share it. You can do this by going to 'System Preferences' > 'Security & Privacy' > 'Privacy' > 'Screen Recording' and checking the box next to Microsoft Teams.
