You can only add a completely new message class using Extended MAPI and C++
or Delphi, not a task I'd even want to consider. So IPM.Contact.Whatever it
is.

See the information Sue also posted about publishing a form using code and
changing a folder default message class.

Thanks Ken, so as I understand it. I can design a form in Outlook, then
distribute that with my addin. Then anytime I add a new item I can use
that form and publish it. So this will create a new messageclass which I
could assign to an object.What if upon starting my add-in I want to create
a new folder and have this folder use my form and also have the default
form be the form I designed. Also do the messageclasses have to extend
from existing. So do I have to have IPM.Contact.MyForm or can I have
IPM.MyForm ?
Thanks so much.
