In addition to the dramatically different user interface shared with other Microsoft Office 2007 programs, Microsoft Office Outlook 2007 also includes a number of improvements and new features: Use the Instant Search option in Outlook 2007 to search for keywords, dates, or other criteria to locate items in your e-mail, calendar, contacts, or tasks. An improved visual design displays each individual result of your search immediately, as soon as it is available, while the search is still running.
