How to access an old MSN email account?

I have a very old email account that I have no idea how to access anymore – even though it’s still listed as an alternate email for security purposes for another really old email account that I have.

It’s an email that ends with ”@msn.com”, but I don’t even know where the log-in page for it would be? It can’t be the same place you log in to access hotmail email accounts, because it doesn’t find my msn email account when I do the “forgot your info” stuff there.

It almost seems to me like the ”@msn.com” email accounts were discontinued, but then I can’t see how my msn account is still listed as the security email for my old hotmail account…

Am I missing something obvious? This is really important to me because I’m trying to gain access to old, personal correspondence.
