Provide an option or feature to show source of message, especially real sender and servers information in Microsoft Outlook 2016
Make an option available to see a sender real address and it would be greatly appreciated to see mail delivery servers route e.g. from context menu.

Ribbon item that allows you to view the message's source code.
Right clicking in a message's body sometimes displays the option to View code, but mostly not sue to the context sensitivity.
Seconding. I can find the headers in properties but sometimes when analyzing malicious email, I want to see what's in the HTML source code of the body without going through several steps and an external viewer.
