Hi @AngieSchwendau ,
Did you get an answer that works for you? Your question really did not include enough detail for us to answer it well. What are you trying to do with the PowerPoint?
Is it a file for students to view, like lessons slides for review? Or do students need to be able to download the files to use on their own?
Does the PowerPoint contain any animations or other special effects, or will a PDF version of the slide show be sufficient? (That is, do you need it to operate as a fully functional PowerPoint file, or do users just need to view content?)
As @Chris_Hofer mentioned, you may (or may not) have an Office 365 integration with your Canvas instance. Do you know if that integration is available to you?
What version are your PowerPoint files? Are you using PPT 365? Have you set the files to "Publish to the Web" or are they native PPT files on your hard drive?
All of these questions are relevant for determining the best advice for posting your PowerPoint content in your Canvas course.
Also, just in case, are you referring to actual Microsoft PowerPoint files, or are you using "Powerpoints" generically for a slide show, such as Google Slides (which would be a different process)?
