Embedding PPT requires Sharepoint login
I am attempting to embed a PowerPoint presentation into a page on my Weebly website. It is successful, in that I can see the PPT presentation after I publish the page, however anyone other than me attempting to view the PPT presentation on my webpage is presented a SharePoint login prompt. I spent a long time working with MSFT support who couldn't figure out the problem so they sent me here. I am able to generate a link to the document that I can send to people, and I can paste a hypertext link to the file on my website which, once selected, will open the presentation, but I cannot embed the PPT presentation w/o the sharepoint login prompt. I am trying to do this because when the presentation is embedded, people can simply view it as a presentation on my website rather than having to open the presentation in PowerPoint online, then go into presentation mode, and go through it that way (I don't want the viewer to have to know how to do all of that.) Thank you for any suggestions. (I ultimately found Powershow.com which may end up being my solution if necessary.)
