When you share a screen, you can share any open program window, or you can share your entire screen. The following steps explain how to do both.
Note
If you want others to see your mouse pointer while you present, you must share your entire screen instead of an individual window.
To share your screen during a meeting
On the call control bar at the bottom of the meeting window, choose Start screen.
The Choose what to share dialog box appears and displays thumbnail images of the applications that you're currently running.
Do one of the following:
To share an application window, choose the desired thumbnail image.
To share your screen, choose Entire screen, then choose Entire screen again.
Choose Share.
Desktop users in the meeting see a Shared screen pop-up, and mobile users see an alert to either view or ignore the shared screen. Meeting attendees who view your shared screen can use their pointers to zoom in and out.
