Outlook 2003 Technical Articles
In this section of the MSDN Library, you'll find technical articles that show how developers can extensively customize the Microsoft Office Outlook 2003 experience by creating and customizing views to better sort, group, and view Outlook items of all types. Outlook also includes the ability to develop custom forms and fields that, when combined with the object model, can be used to develop custom solutions.
You can use the TOC to your left to navigate through the Library articles.
