How do I view the header information of an email message?

The following article explains how to view the header information of an email message. The header of an email message contains information about the path an email message has taken. It shows the different mail servers it has gone through as well as where it originated from. An example header is below:

Microsoft Mail Internet Headers Version 2.0
Received: from   safesecureweb.com ([209.41.168.152]) by server.safesecureweb.com with Microsoft   SMTPSVC(6.0.3790.211);
