You can't create an account unless your have a mail profile to contain it.

When sending from Outlook Express to this account on Outlook, the
postmaster says
the server rejected it.

And the exact text of that error is?

Since I can send emails without a problem, I did what you suggested
and sent an email to myself but interestingly enough, my email
address does not automatically appear in the "From" box like it does
in Outlook Express. Is that normal?

The From field in Outlook is not applicable in a situation like yours where
you use a POP account. The From field in the compose window isn't used for
specifying the sending address.
