Do you have a Hotmail email account?
Are you trying to send an email to a Hotmail account?

Looks like you're trying to use Hotmail with Outlook as a POP3 email account. Unfortunately, this can't be done without subscribing to that service, which is why it's telling you that you need to register.

Your second option is to download and install Windows Live Mail.

If you have a Windows Live Hotmail Plus subscription, you can use a POP3 (POP3, or Post Office Protocol 3, is a protocol that's used to retrieve e-mail from a mail server.) server to add your Windows Live Hotmail account to Microsoft Outlook Express and access messages there. If you download and install Windows Live Mail, you can add your Windows Live Hotmail account to Windows Live Mail and access your messages and contacts there.

You can get Windows Live Mail from HERE.
