Returns the entry identifier for the initial address book container.
Client applications and service providers call the GetDefaultDir method to retrieve the entry identifier of the default address book container. The default container is what the user sees displayed in the address book when the address book is first opened. If a default container has not been set by a call to the IAddrBook::SetDefaultDir method, MAPI assigns as the default container the first container with names that is not the personal address book (PAB). If such a container cannot be found, the PAB becomes the default container.
To set the default directory, a client or provider calls the SetDefaultDir method. Clients and providers do not have to call the IMAPIProp::SaveChanges method; because changes to the address book are not transacted, changes are immediately made permanent.
