View a Message's Source in Windows Mail or Outlook

Normally, we're more interested in an email's text than we are in its source. But sometimes, taking a look at the source can be interesting, or necessary.

Especially when something does not work right, the message source can often lead to a clue what went wrong, and the source often reveals a spammer's ISP, too. Fortunately, Windows Live Mail, Windows Mail,​ and Outlook Express offer a smart shortcut that brings up a message's source quickly.
