PDF preview issue in SharePoint

[Sagar Patel]

While user try to access PDF file message popup "Hmm...looks like this file doesn't have a preview we can show you". 

Office 365 Group -> Files->Browser Library -> Document

Is there a way to fix this issue in SharePoint?

Thanks

It could be a protected PDF file then it can not generate a preview.

Hello Paul,

I verified it is not protected pdf file. it open usually without any error. but in rare case it throw error for " PDF preview ".

Thank you

I had the very same issue, the original document was a PowerPoint.

After some attempts I got it to work by creating the PDF directly from PowerPoint through the option "Export".

Hope that works.

Error prompt through Browser, not from Office 365 application. but seems its working now. I think it was Browser error! through update it work fine!

@Sagar Patel, what updated did you do to fix this?

Which webpart did you test - File viewer or Highlighted content - or both?

I had the same problem.
I discovered on another forum that this is caused by the length of the filename. I shortened the filename and sure enough, the preview displays.
