What do you mean by "override"? The Outlook object model allows you to create, modify and delete appointments.
FYI, there is a newsgroup specifically for general Outlook programming issues "down the hall" at microsoft.public.outlook.program_vba or, via web interface, at http://www.microsoft.com/office/community/en-us/default.mspx?dg=microsoft.public
.outlook.program_vba
