you can see any POP-enabled e-mail account (including Yahoo! Mail (Plus), AOL Mail, and Gmail) right from your Hotmail account. You can put all of your messages together in your inbox or each e-mail account in its own folder, your choice.
You can set this up in Hotmail in three simple steps:
(1) Click Add an e-mail account on the left-hand side of the Hotmail inbox.
(2) Type the e-mail address and password for your other account, and click Next.
(3) Choose where you want the messages to go, and click Save.
