Outlook 2003 : View Message Source?

Since my last format a few weeks ago (it has been 1.5 years since — rather spectacular imo), I switched from Outlook Express to Outlook 2003.

A feature that I have been missing in Outlook is the ability to view the source of the message (handy when you are in doubt if a message is genuine or if it’s just an other (uncaught) virus/spam message).

You have the option to view the headers (Right click on the message > Options), but the message source isn’t shown in that box 🙁

Now long live the world wide weirdness since actually it’s plain easy:

  • Open the registry editor. (Start Menu -> Run -> "regedit")
  • Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Options\Mail
  • Right click on the right pane and choose New -> DWORD Value.
  • Type SaveAllMIMENotJustHeaders into Name.
  • Right click the new item you created. Type 1 into the value box.
  • Close regedit and restart Outlook if it was running.
  • Right click on the message and select options to view the source in the box named "internet headers".

But what the sites don’t tell you is that this only works on newly retrieved messages … thus making this interesting enough to mention here 😉
