We are trying to see if PowerPoint packaged as ppsx files can be embedded in Canvas. Microsoft Office Mix was the previous solution but Microsoft is closing this down on 1 May 2018.
I tried the Microsoft Office LTI but it did not seem to work. The best I have been able to do is allow the file to be downloaded from Canvas then opened using the PowerPoint application to open and play.
I would be interested to see if anyone has found the Microsoft Office LTI to work with PowerPoint files - and ones that has quizzes built in?
