Motorola V710

Does anyone know if it is possible to get to Outlook Web Access (OWA) or Outlook Mobile Access (OMA) from the v710? From a normal web browser, an authentication dialogue box pops up and you enter your username and password. It doesn't seem like the Openwave browser supports this method of authentication (like my Blackberry does, for example). I'm guessing Verizon is determined to keep you on their sites, paying for everything (yet another email account, for example) but maybe I'm missing something. Thanks.
