i send an encrypted email to someone, the message is encrypted using their
public key. the message can only be DEcrypted by the users private key... so

It gets encrypted when sent. You only have a copy. You do NOT have a
copy of what actually got sent (i.e., what you delivered to your SMTP
mail host). You only have a *local* copy of your e-mail. Obviously you
can read whatever YOU sent. There would be no point in saving a local
copy if you couldn't read it. Have you tried BCC'ing yourself on the
encrypted e-mail and then yanking back a copy of what actually got sent
and then trying to read it?

while that answer is ok for outlook, it doesnt work with windows mail or
outlook express.
when you send an encrypted mail with either of those clients, you can NOT
read the copy that is in your sent items folder. see? learn something new
every day huh? so thats why im asking... why does it work in outlook.

Who cares? This is an Outlook newsgroup.

And I would care WHY about other e-mail clients than this newsgroup
addresses? You asked about Outlook. If you want to know how other
e-mail clients work then go ask in the newsgroups for THOSE other e-mail
clients. Could be Eudora, Thunderbird, Forte Agent, Pegasus, and other
e-mail clients all behave differently from each other. That is
irrelevant in a newsgroup that discusses *OUTLOOK*.

LMAO its funny that none of you morons care to learn anything new. are you
not curious how email encryption works in general? or how outlook handles
it? because none of you know. why cant OUTLOOK view sent encrypted items in
the preview pane? why do they need to first be opened? hhmmm.... MVP's huh?
sure, as long as someone is asking how to open a freakin PST file! soon as
you get an intelligent, real world question you all choke and get defensive.
its comical

I know both of these quite well. I run the PKI service where I work.

Because that's the way Outlook was designed to work. We who are MVPs don't
have links into the minds of the developers. You'd have to ask them for
their reasons.

You're the one who said "why can i read the message in my sent items folder
in outlook?" Now you're saying "why cant OUTLOOK view sent encrypted items
in the preview pane?" You seem to be contradicting yourself. Your second
statement seems to be the true one. But again, it is what it is. The
reason appears to be that not only is the message encrypted using the
recipient's private key, it is also encrypted using your own private key, so
you must decrypt it to read it or, at least, so my experiments seem to
indicate. Why a message in the Sent Items folder would behave as though it
were sent to yourself, however, cannot be known except by the people who
wrote the program.

Do you also ask for /help/ regarding the selection of tires by going to
a gardening newsgroup? You were the one that became defensive. We were
poking fun at *YOU* for being the boob while you whined like a child
that "it don't work the way that *I* want, waaaaah". If someone is
pointing a gun at your head to force you to use Outlook, do you want us
to dial 911 for you?

I meant to type "your own public key".
