Email content is not displayed in Hotmail/Outlook.com/Live.com but displays fine in GMail

When I receive a specific email message that is auto-generated from one of the sites I use, I cannot view the content on Hotmail.com.

All messages I receive on hotmail are forwarded to gmail and the same message does display in gmail.

Furthermore, there is no warning in Hotmail about some content not being displayed for security reason and no option to display it.

If I look at the DOM for the content DIV element, it is shown to be empty.

Please contact me if you have any idea or need more information, I can send the HTML of the email for which I experience the problem.

I would very much like to identify what in this HTML is causing the issue in Hotmail.

Thank you kindly.
