How To: Get Hotmail on Outlook/Thunderbird | Posted at 3:21 PM
Recently the Windows Live team enabled POP email access for all Hotmail (Live Mail)-based accounts. I found a great resource for how to add your accounts to Outlook (and with Thunderbird it's pretty much the same).
In Thunderbird, for incoming you choose POP. For outgoing (SMTP), you need to add it in the Outgoing Server account and instead of SSL, choose TLS with a port 25. Type in your username as well.
Yes, it works with Hotmail-based accounts too, like my Student Partners email address.
