The method depends on the version of Outlook. With the exception of Outlook 2003, Outlook displays only the headers, not the full message source. If viewing headers is something you need to do often, use a utility or VBA code to view and copy the headers.
Beginning with Outlook 2003, you can view the header and full message source together by adding the SaveAllMIMENotJustHeaders value to the registry. For more information and ready-to-use reg files, see View the Message Source in Outlook
For a more readable copy of the Internet headers in Outlook 2007, 2010, or 2013, use a VBA macro to create a readable copy the headers in a new message form. Get the code sample from Get Outlook’s Internet Headers using VBA.
