Accessing Item.To in outlook VBA

Question

In a macro I need to access the names in Item.To while typing an email.
For example while typing the email goto the tools menu and run the macro from the 'macro' submenu.

When the code trys to use Item.To there is a debug exception and the debug tool tells me "Object required".

I can access Item.To durring Application_ItemSend, so I have part of it right.

Thanks for thinking about it, I am stuck on this one!
