Is it possible to spoof the From: field in Outlook?

I am wondering if it is possible to change the From: field (not just the reply-to) in Outlook (specifically in the 2010 beta, but also interested in other versions).

"Try the following commands (type them into a command prompt and press Enter after each one):

telnet smtp.mailserver.com 25
HELO QA
MAIL FROM:yourid@mailserver.com
RCPT TO:yourid@mailserver.com
DATA
Subject:test mail
This a test mail
.

The last command is a dot (.), to end the email. Replace ""mailserver.com"" with the URL of your mail server, of course.

If you see a message like the following, then it means you've successfully spoofed the sender email:
