Trabajando con Listas de Distribución de Outlook usando la Biblioteca de Correo C++

Trabajando con Listas de Distribución

Es posible crear una lista de distribución utilizando la API de Aspose.Email, que es una colección de múltiples contactos. Una lista de distribución se puede guardar en disco en formato MSG de Outlook y se puede visualizar/manipular al abrirla en MS Outlook.
