Yes. If a content add-in is embedded directly in a PowerPoint slide, your colleague can view it without installing the add-in separately. The same applies to content add-ins in Excel and OneNote. Example add-ins are Web Viewer 2.0 and Timer for PowerPoint.
What your colleague needs to do
- Open the slide that contains the add-in.
- When PowerPoint asks for permission, click Allow and Continue.
- View the live add-in directly on the slide.
Does your colleague need their own subscription?
No. If you subscribe to Web Viewer 2.0, anyone you share the presentation with can view the Web Viewer slides you added, without a subscription of their own.
