Open msn mailbox

I'm happy to help! However, I need to clarify that MSN Mailbox is no longer available. MSN (Microsoft Network) was a service that was discontinued in 2013, and its email service, MSN Mailbox, was also shut down.

If you're looking to access your old MSN Mailbox emails, I'm afraid it's not possible anymore. Microsoft has deleted all the data from the MSN Mailbox service, and it's no longer available.

If you're looking for an alternative email service, I can suggest some popular options like Gmail, Outlook, Yahoo Mail, or ProtonMail. Let me know if you need help setting up an account or migrating your emails to a new service!
