Please stop posting incorrect replies. The "From" field has NOTHING to do
with the Outlook address book - it's there for when a User sends a message
on behalf of another user, generally in an Exchange environment.
In fact, if you use the From field to specify one of your contacts or you
enter your own value here, the result is "xxx sent on behalf of yyy". The
From header will have this value but the Sender header will show the e-mail
address that you specified in the account that you defined in Outlook.
Account's e-mail address: (e-mail address removed)
From field's value: (e-mail address removed)
Recipient might see: (e-mail address removed) sent on behalf of (e-mail address removed)
Even if their e-mail client doesn't reveal the inconsistency, the headers in
your e-mail will have:
From: (e-mail address removed)
Sender: (e-mail address removed)
So you won't be lying to the recipient as to who really sent that e-mail.
If you want to lie, you'll have to edit the E-mail field in the e-mail
account that was defined in Outlook (but recipients can still see your
sending mail server to know the originating domain, and some use SPF which
can be used to track through the logs to see just who was the original
account used to send the e-mail assuming the sending mail server doesn't add
that info itself in another header).
