In Outlook you can drag and drop between pretty much any of the types of items and Outlook handles it accordingly. Such as drag a contact with an email address to the inbox to address an email. In another post I just listed the code for a macro to create a contact from a custom form. I can run the macro from a toolbar button or from Tools, Macros. Is there an event or something that can trigger this macro when I drag from my email folder to my contacts folder using this custom form? Or asked generically, how does one code for drag and drop?
