Wait...
Was your address @msn.com... not hotmail.com?
If so, then yes you may lose your messages. Forward all of them you want to save to another box before your service terminates.
Nope.
I am still using my msn.com account from Hotmail.com right now as we speak, and I cancelled my msn dial up ages ago.
I have a msn.com address.
I can access thru Hotmail, but I think my old email may go bye-bye once I cancel MSN dial-up.
Thoughts?
