Yahoo %26amp; gmail provide instructions about it. CHeck in the settings patge of your mail account to look for exact instructions. Few like rediff.com charge money for this service. You can add only SMTP or POP3 in outlook, not HTPP. You basically have to ask your e-mail provider how to do this. They will be glad to tell you that.
