HTTP mail service account could be accessed in many ways: HTTP mail web interface, Microsoft Outlook Express and Microsoft Office XP Outlook. But there is some drawbacks using this methods. Web interface seriously limits mail client functionality. Outlooks Express is powerful mail client but convenient work requires some additional features: advanced contacts information, notes, tasks, etc. Other serious drawback of Outlook Express is absence of HTTP mail account messages filtering support. Office XP Outlook eliminates most of other clients weaknesses. But both Outlook Express and Outlook XP implement message store functionality model. This model is not convenient for message filtering and offline work. And at least you don?t need an additional investments in Office XP if you already using Office 97 or Office 2000.
