Launching a PowerPoint file in Slide Show view from Sharepoint Online
Thanks for your reply, but I've tried that as well.
I originally saved my PPTX as a PPSX, because I wanted the file to launch as a PowerPoint Show. I saved it in Kiosk mode, because I wanted my users to click the Actions Buttons in order to progress throught the slides. Unfortunately, when I put a link to it in SharePoint, it just opens in Normal View instead of Slideshow View. I tried embedding it, but is disables the kiosk aspect of it.
If I could just get it to launch in the desktop application in a PowerPoint show. I've seen in other forums that you just need to add a bit of text at the end of the URL. Something like PowerPointView=PowerPointShow, but I don't know what prefixes it.

Could Microsoft be proactive or perhaps let us know when Sharepoint will have a more usable solution? - simondelisleDec 21, 2021Copper ContributorOK so I do finally have a solution that I found here:

 In short, open the PPTX file in SPO in Editing mode. In the URL you will see "?action=edit". Change that to "?action=embedview". It seems to work perfectly. It would have been nice if someone from MS could have just answered that 4 years ago...
 As an aside you can even open to a specific slide by adding "?action=embedview&wdSlideId=slideId". Of course, getting the slideId is proving tricky. I got it once but now I cannot figure out how I did it!
