Outlook 2010 is Microsoft's email program and information manager, available as standalone product or bundled with Office 2010 Home and Business or Office 2010 Professional.
Outlook 2010 is the last core application to adopt the Ribbon instead of menus; Outlook 2007 had it in dialogs (like email, appointments, etc.), but kept menus in the main window.
The Ribbon uses new keyboard shortcuts, but you can still use the classics: Options is now "Alt+F, T", but pressing "Alt+T, O" still works! (used to be "Tools > Options").
Like its predecessors, Outlook 2010 includes a full-fledged email program, an advanced contact manager, a calendar, and lets you write tasks and notes. Best of all, everything is indexed and searchable (even when using Windows search, outside Outlook!)
What's new in Outlook 2010? Smart improvements like "Quick Steps", and a slew of minor ones. It's a marginal upgrade for Outlook 2007, but substantial coming from earlier versions.
