Launch PowerPoint files into slideshow in Office 365

Tech Trek – 2018.06.13

I’ve had a blog post to open a PowerPoint file into slideshow mode back in SharePoint 2010 version.

In SharePoint 2013 and Office 365, the link no longer works since PowerPoint.aspx was replaced by WopiFrame.aspx page.

Below is the updated link to launch into slideshow mode.

In SharePoint 2013, 
https://<siteUrl>/_layouts/WopiFrame.aspx?sourcedoc=<fileUrl>.ppsx&action=embedview
In Office 365, 
https://<siteUrl>/:p:/r/sites/<siteName>/_layouts/15/Doc.aspx?sourcedoc=<guid>&action=embedview

The key change is replacing the action parameter with embedview so that animations can be displayed. The manual method is to click Start Slide Show when the PowerPoint file opens in Office Web App.

Start-SlideShow
