I log into my outlook email through Firefox browser. When I click on a pdf attachment I get "something went wrong while the document preview was being created Try again later". I can download it and open with adobe reader but the preview won't open. The pdf preview is working fine if I use Microsoft Edge to open my email. There has to be something with Firefox that is preventing the preview from loading.

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:

https://outlook-1.cdn.office.net/owamail/20210927003.01/scripts/owa.vendors~SxSPdfWorker.js

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 using Firefox’s built-in viewer.)
