I've called the IMAPISession::OpenAddressBook()
function. Unfortunately, unless you are running
a mail client such as Exchange or Outlook, the
function reports that MAPI was unable to load
the information service emsabp.dll. Sure enough,
I can't find this DLL and can't find any
reference to it on the Microsoft site.

I reckon this might be the cause for problems I'm
having creating entries in the personal address
book programmatically. I can only create entries
if a mail client is running in the background.

Does anyone know anything about this or know
where I could get hold of the DLL?
