Present a Local File From PowerPoint app to PowerPoint Live in Teams

Good news for PowerPoint users! The "Present in Teams" feature has been enhanced in the PowerPoint app to enable presenting files that are not stored in Microsoft 365 Clouds. This can now be done by using the "Present in Teams" button in the PowerPoint app for Windows, even if the file is not stored in Microsoft 365 Clouds. This means that users can now present via PowerPoint Live in their Teams meetings, using a new entry point for those files. Clicking "Present in Teams" prompts users to save the file to Microsoft 365 Cloud, after which PowerPoint Live automatically begins to present the file in the current Teams meeting. Please note that this update is currently only available for the PowerPoint app for Windows, and is not yet available on the Mac app. This message relates to Microsoft 365 Roadmap ID 117477. The feature will begin rolling out in early July in Current Channel, and is expected to complete by late July. No action is required from you at this time, just inform your users about this extension.
