You can "recall" the message. :-)
No you can't. I can't tell if by the smiley you are really joking or
Sometimes you can. In the past it was considerably more possible, but
vandals resulted in the feature being removed from a lot of stuff.
In some versions of Outlook you can recall a message, and if it hasn't been
read already, it will be deleted from the recipient's inbox. I believe it
will be deleted if it is still sittong on an Exchange server. Of course,
that only works in some versions of Outlook. In others the recipient gets
the recall message, as you note.
It used to be possible to send a delete to a usenet newsgroup to try to kill
a message previously sent, and it would be deleted from the servers. Didn't
help if someone had already read it, and didn't help if the delete arrived
before the message. Most usenet servers I believe have long since ignored
delete requests after some kid started spam-bopming newsgroups with delete
requests for every message in the ng.
So yea, most of the time you can't. But sometimes you can. It mostly
results in confusion when it works because some people see the message and
the guy in the next cube doesn't, and wonders why he was singled out to not
get the company-wide payroll suspension announcement.
