Enviar correos lotus desde excel

Tengo una macros que debiera enviar por correo la inf. De la hoja1 que tiene 1 destinatario y la hoja2 que va a otro destinatario y asi puedo llegar a tener mas de 20 hojas con destinatario diferentes y los correos se envían bien dentro de outlok pero llegan con el cuerpo o información en blanco osea no estoy especificando bien el rango porque debiera ser variable ya que cada hoja tiene una tabla dinamica diferente que se actualiza todos los dias entonces el largo de la tabla es variable y ahora resulta que me cambiaron el correo de outlock a Lotus notes les deo mi macros para que me puedan ayudar.
