Until now, Microsoft only allowed clubbing upto 4 Live mail accounts into one. Now the team allows you to collect your Gmail, Yahoo! mail, and other foreign email accounts to your Hotmail account to centralize email from various sources, allowing users to check all their content via a single email account.
The catch is that adding new email accounts will work seamlessly for most large e-mail providers and Internet Service Providers. All that end users will need to do is enter the desired email address along with the associated password and you'll have no problems to POP - and SMTP servers and gateways. All these institutions we have put for you.
Additionally, you can choose whether you want to receive your foreign email in your Hotmail inbox or you want to receive in a separate folder. You can also use a color code to each account you add, so you can see what e-mail account the e-mail is received.
