Exchange Server 2007 SP1 includes a slew of improvements to Outlook Web Access (OWA), the Microsoft Outlook web-email client. If you’re already used to working with the OWA interface in Exchange 2007, you won't have any trouble navigating OWA in Exchange 2007 SP1. Although Microsoft has added new features to OWA in SP1, it hasn't changed how you implement previously existing features, nor has Microsoft altered the steps you need to take to perform various tasks. Here I introduce you to some of the SP1 OWA enhancements and explain how these features provide a better webmail client experience for your end users.
OWA Light
Like many previous Exchange versions, Exchange 2007 includes a lightweight version of OWA—called OWA Light—intended for users with low-end browsers, such as the ones used on Windows Mobile devices, or Mozilla Firefox or slow Internet connections. To use OWA Light, go to the OWA sign-on screen and select the Use Outlook Web Access Light check box, as Figure 1 shows. As you see in Figure 2, OWA Light has the same basic features as the full-blown version of OWA (e.g., message list, calendar, contacts, and mail folders). However, it contains far fewer features than the complete OWA, omitting features such as the Tasks module and task-specific properties, mail-item search, reminders, flags and categories, the ability to compose HTML messages, the Free/Busy grid, and deleted-item recovery, among others. . . .
