I'm having a problem for one user in our organization. When using PowerPoint 2016 (Office 365) we are not able to browse to a file when using the Reuse Slides function. The pop-up window appears to be only looking for PowerPoint files on the local computer, SharePoint, and One Drive. I'm not sure if this is an issue with the fetch file function or not. Below are a few points of interest.
1. This is only happening with a single user on the computer. Other users can log in and use the function without issues.
2. Starting PowerPoint in Safe Mode appears to resolve the problem. However, disabling all add-ons does not affect the problem.
3. For the affected user there is an additional "Reuse Slides" button on the ribbon, next to the "New Slide" button, that is not present for other users or in safe mode.
4. This "Reuse Slides" button cannot be removed from the ribbon.
Any information would be greatly appreciated, thank you.
