I believe that after 270 days (9 months) of inactivity on a Microsoft email account (msn, live, outlook, hotmail) all messages are permanently deleted. After an addition 3 months (one year of inactivity) the account is completely closed. So if you haven’t logged into your msn email account in over one year it is probably gone forever and you won’t be able to get that (or any other) .msn email address.
