Microsoft Outlook is Microsoft Office's premier messaging and collaboration client for the Internet and Microsoft Exchange.Some highlights of Outlook 2000 development capabilities: * Formerly known as OLE Messaging and Active Messaging, CDO is an object model that gives applications more direct access to the Messaging Application Programming Interface (MAPI) used by Outlook to structure its data storage than does the Outlook object model. Programming with CDO is more flexible than MAPI because, unlike MAPI, CDO does notrequire C or C++ as the programming language. * Along with other Microsoft Office 2000 applications, Microsoft Outlook 2000 allows you to enhance and extend the application by using Component Object Model (COM) add-ins. * Team Folders makes it easy to build sophisticated team-collaboration applications with Outlook and folder home pages simply by running a wizard. Team Folders provides templates for such applications as group discussion, document libraries, and team calendars.
