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,

    Very thanks for your update.

    Yes, you can run PowerShell commands to add pdf as the allowed file types. Please invite an Office 365 admin and perform the below steps:

    1. Connect to Exchange Online PowerShell with an Office 365 admin account.
    2. Run this command to check the AllowedFileTypes in your organization

    Get-OwaMailboxPolicy OWAMailboxPolicy-Default | select -ExpandProperty AllowedFileTypes

    1. Run this command to add PDF to the AllowedFileTypes

    Set-OwaMailboxPolicy OwaMailboxPolicy-DefaultMailboxPlan -AllowedFileTypes @{Add = '.pdf' }

    Note: Please replace OwaMailboxPolicy to your Outlook Web App policy’s name.

    Regards,

    Barry

    Hi BuckyBear3819,

    Thanks for your update.

    We think that the problem may be related to the PDF file. We will give you a sample file in private message. Please check if the problem persists in your tenant.

    Meanwhile, we’d like to know more details about your situation. Can you open other types of attachments in the affected tenant? For example, Word, JPEG?

    Also, please tell us your current OWA version.

    Regards,

    Barry
