The root cause is that the window being shared is the PowerPoint Normal view window, not the Slide Show window.
Based on the Online Help Sharing PowerPoint Presentations in Engage Meeting, to share the content displayed in the PowerPoint application in an Engage Meeting, users must start the slide show in PowerPoint before sharing their screen since the slide show displays in a separate window from the PowerPoint application.
To resolve the issue, the Engage Meeting host can continue to do the following steps to share the Slide Show window during the Engage Meeting:
- Start the presentation from the Slide Show tab in PowerPoint.
- Navigate back to the meeting navigation menu and select New Share.
- Select the Slide Show window from the prompted window.
- Select Share to share the presentation in the Engage Meeting.
