Typically, when you receive an email in your inbox and open it, you see very basic information at the top of the message, including who the email was sent by, who it was intended for and when it was sent. Using the Internet headers feature of Microsoft Outlook, you can also find out server information about an email message or address, which will tell you the path the email traveled after being sent.
Open the Start menu and click on the "Microsoft Outlook" icon.
