Through Windows Live Mail, you can manage all your e-mail accounts including Hotmail and third party accounts from within Windows Live Mail. Now you don’t have to log in to multiple accounts.
To use a Windows Live Hotmail account in Windows Live Mail:
Open Windows Live Mail > Tools > Accounts > Add.
Here select Account type; in this case Mail. Click Next.
You will have created the account. Select if you’d like it to be the default mail account.
