I've just started to use Outlook 2007. Previously, I used Outlook

source code of a message before opening the message.

Not even possible in Outlook Express. Thank about it: how could you
possibly see the contents of something without opening it. The View Source
option in OE _does_ open the message; it just doesn't render it.
