Can I play a PowerPoint presentation on my site?

Yes.

 

You cannot place a PowerPoint presentation directly on a page in your site, however, you can upload the presentation to My Files, and then create a link to the file from a page in your site.

 

If you want to share a traditional PowerPoint presentation such as sermon notes, conference materials, etc., you might want to consider using a service such as slideshare.com to upload the presentation and share it directly from your site.

 

If you want to share a photo slideshow, see How do I add a slideshow to my site?
