As far as I have been able to find out Hotmail only allows you to set up POP accounts to pull in traffic from up to four other email accounts. I have never been able to find where Hotmail provides the POP or STMP addresses for you to set them up in Outlook or any other email utility.
If you want to use a free web based email service which allows you to set up their POP and STMP addresses within Outlook check out Yahoo. I'll fore warn you that getting the STMP to work correctly is a little tricky. If you need help getting it to work correctly, checkout Yahoo's online help first, and then if you still need help, let me know.
One thing you will need to be aware of up front is Yahoo requires you to attempt to receive your emails before you can send your outgoing mail which conflicts with Outlook 2000 which attempts to send before it receives. So to get your outgoing mail sent, you will have to press Outlook's send/receive button once to get your mail and then a seccond time to have it send your mail.
Hope this helps. s-) -Bobby
