Can't repair a PowerPoint presentation? Try this...
This only applies if your PowerPoint file is saved under Onedrive.
This applies if you get the following message, and clicking "Repair" results in a corrupted presentation.
Try using the browser-based Repair, like this:
1. In File Explorer, right-click on the .pptx file
2. Select "View online". This should open a browser-based version of PowerPoint.
3. Click on the file name in the orange ribbon. You should see the following pop-up.
4. Click on Version History. You will see a list of previous versions of the file.
If you are lucky, the previous version will not be damaged.
But if you are unlucky, ALL the previous versions could be damaged.
The main point is that the online repair works better than the Windows-based repair.
5. Select each previous version of your file and repair each one (if it is damaged)
until you have recovered the most number of slides possible.
6. You can open a new presentation (File / New) in your browser, and copy individual slides into it from previous versions in order to create a new file of undamaged slides. When you save this file, it will automatically be downloaded to your desktop.
7. From the top ribbon, select Editing / Open in Desktop App in order to test
whether your new file is working in your normal desktop version of PowerPoint.
This worked for me, and saved me hundreds of hours of lost work.
