Cannot Preview PDf in OWA

I would very much appreciate some help on this.

When trying to preview a PDF file extension in the Outlook Web App the following error is generated. "Something went wrong while the document preview was being created. Please try again later."

This is only appilcable to PDF extension files and not a Word or Excel entension file. It also only happens in Firefox and not Edge. This has not in the past been the case in Firefox and is not related to updates of Firefox or settings none of that I have changed. This behaviour also happens across multiple systems. Your help or assistance would be very much appreciated. Dave

Hmm, two other users just posted about a problem with previewing PDFs on Outlook. Possibly there was a change on the site, or to an add-on popular with Firefox users. I'm sure we'll be learning more in the coming hours.

One possible reason for the inability to preview is that the page is requesting a file that doesn't exist:

the 20210927 in that path looks like yesterday's date, so I suspect there was a recent change on the site.

Currently, I think the only workaround would be to use the Download option to view the PDF in a separate tab. If you have the default setting ("Open in Firefox") or prefer to always get the download dialog ("Always Ask"), then Firefox will offer this option. If you set Firefox to always save PDFs or always open PDFs in another program, then that would happen instead. (To view/modify PDF handling settings, see the steps in this article: View PDF files in Firefox or choose another viewer.)

Hi Jscher.

Thank you for having taken sometime to look over this for me and for posting the workaround for the meantime.

I guess for now one might have to wait until some form of resolve can be implemented.

Many thanks
