OWA allows access to email, scheduling (including group scheduling), contacts, and Exchange folders. You can drag-and-drop, use pop-up menus, toolbars, out-of-office settings, and delegate access to your calendar. You can double-click to create appointments and meetings, view meeting reminders in pop-up windows, search your mailbox, and view and edit distribution lists stored in your contacts folder. Using Internet Explorer, OWA functions much like a standard version of Outlook. (Other browsers can be used, but may not be as functional.)
