  • Missing slide content

The issue is seen most frequently when uploading slides containing:

  • Multiple images
  • Math equations
  • Complex backgrounds
  • Certain fonts


Convert the PowerPoint to a PDF (Recommended)

Follow the advice here on how to address possible issues with the PPT slide content, convert the PowerPoint to PDF, then upload PDF file to Collaborate:

Best Practice for PowerPoint Slides

Send to another moderator within the same session

Sometimes the PowerPoint will not upload for you, but it will upload for your colleagues within the session.

Send the PowerPoint file to another Moderator within the Collaborate session and see if they’re able to upload from their computer.

Export PowerPoint slides to image files, then upload as images

An alternative is exporting from PowerPoint slides to image files, and then upload the image files instead of the PowerPoint file to the Collaborate session.  (Note: Screen readers can only read text on PowerPoint and PDF files, not on image files).

Use Share Application to share the PowerPoint from your desktop

Share Application works in the Google Chrome, Microsoft Edge and Firefox (Version 49+).  This is another alternative if you’re unable to upload your PowerPoint and don’t necessarily have the time to troubleshoot the other options.

(Note: Application sharing uses more bandwidth than uploading files. Additionally, when sharing a PowerPoint slideshow, you must share the entire screen to display the slideshow).
