Assume that you use Microsoft SQL Server 2016 Reporting Service to create a subscription, and you configure it to generate a report as a PDF attachment. After the subscription is run, you receive the email attachment. However, you the attachment is not recognized as a PDF file by some email clients.
This issue occurs in Reporting Service 2016 because the MIME content type inside the email message is set to the Application/Octet-Stream type instead of the Application/Pdf type.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
