I think it may have always worked this way. Outlook was never really
intended to have security or integrity. If this bothers you, you should
do the same experiment on a digitally signed e-mail. Same result, but
the scary / amusing part is that you can click on the button to verify
that the message was not altered and it will STILL VERIFY. So, the
process that verifies that the message wasn't altered during
transmission DOES NOTHING to show that the message was altered AFTER
RECEIPT.

Hey, I've got this digitally signed e-mail from my boss saying that I'm
immediately getting a 30% raise, retroactive to my first day with the
company.... ;)
