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!

    Hi BuckyBear3819,

    We have been aware of the issue now, and our engineer are working on the issue. Currently, there is no update at this time. We will keep you updated once we get further information. Thanks.

    Regards,

    Johnny

    If you look closely, OWA changes the file code.

    The header of the file changes from pdf to html.

    If I download the file it says that it is damaged but if I forward the mail, the attachment can be opened ok in another mail client.

    This does not happen with all PDFs, only with those of a sender.

    Only happens in OWA, in desktop outlook works perfect

    As a workaround, we recommend that you enable Direct File Access, block all the file types and only allow PDF file type in your organization. For more details, see this article: https://docs.microsoft.com/en-us/powershell/module/exchange/client-access/Set-OwaMailboxPolicy?view=exchange-ps

    Hi  - Is there any update on this one please? Johnny's comment suggests that this is an issue at Microsoft's end, is that right?

    We're seeing EXACTLY the same issue with our tenant as BuckyBear3819 has reported.
