I would like to add new features to Microsoft Outlook. I need my program to work on the largest install base of Outlook : Outlook 2000, Outlook 2002 and Outlook 2003.
Is it possible to have a Outlook add-on that works on all these versions? What are the limitations?
What is the best ways to program Outlook? VB, VBA, Outlook forms, Visual C++? What are the advantages and limitations of each method?
