The HP Jornada 520 or 540 series Pocket PC with a CompactFlash modem can now be set up to use MSN E-mail.
MSN's POP3 (Post Office Protocol 3.0) e-mail server uses a unique security feature named Secure Password Authentication (SPA). Previously, only Outlook Express, Outlook, and Hotmail could work with SPA and retrieve MSN e-mail. The Pocket PC's Inbox needs the MSN E-mail for Pocket PC add-on in order to retrieve MSN e-mail. This add-on modifies the Pocket PC Inbox to work with MSN's SPA-POP3 server.
