Cannot Preview PDF attachments in Outlook Web Access

We have Exchange on O365 and User desktops of Outlook 2016.  Some users have Outlook on their mobile phones also.

We can preview PDF files in Outlook emails on the Desktop Outlook and on mobile phone with outlook.

We cannot preview PDF files in Outlook on the web browser.  We can preview office files but PDF files display a blank grey page.  

We can download PDF files to onedrive and open and view them from onedrive.   

  1. Should we be able to preview PDF files in Outlook on the Web Browser?
  2. Can this be enabled to work?

Thank you!

    Hello BuckyBear3819,

    According to all information we collected, we think the problem is not related to the Office 365 side.

    If you right click on a PDF file on your computer and select open with Internet Explorer, will you encounter the same issue?

    We need a sample file of the PDF file for test. Please remove the privacy and send us a sample file in private message for analysis. Your cooperation is highly appreciated.

    Regards,

    Barry

    Hi Barry and thank you for your efforts on this question. 

    Yes, Edge was the default browser on my Win10 laptop. 

    I switched it to IE11 and it still has the same issue.  in IE it displays a grey preview window when previewing the PDF File.  (I get the same behavior on my Win7 PC with IE11.)

    OS Name:                   Microsoft Windows 10 Enterprise

    OS Version:                10.0.16299 N/A Build 16299 

    I can save the file to my onedrive and open it without issue on both Win10 and Win7 using both IE and Edge. 

    I Appreciate your time on this,

    BuckyBear3819

    Hi BuckyBear3819,

    May I know if Edge is your default browser or not? Based on my experience, lots of people will see the “Something's keeping this PDF from opening” error if the default browser is Edge. Try changing the default browser to another and check if it helps.

    Also, please copy the URL address and open the file by this URL in your Acrobat program as a temporarily workaround.

    Finally, we need the detailed version of your Windows 10 system. Your cooperation is highly appreciated.

    Regards,

    Barry

    No luck on that solution.

    i tried adjusting the User Account Control and i also made sure the PDF file type defaults to Adobe and it still gives me the same failure to display the PDF doc.  

    I'm wondering if there is some policy that is preventing PDFs from opening in the browser.

    Hi BuckyBear3819,

    Thanks for your information.

    Based on my research, this kind of issue can be solved by changing the value in User Account Control Settings. Please open your control panel and search for User Account Control Setting. Then change the setting and check if this problem can be solved.

    Regards,

    Barry
