Non uso OutLook, quindi non posso provare, ma questa mi sembra la soluzione.
Sub SMAIL2()
Dim OLook As Object 'Outlook.Application
Dim MItem As Object 'Outlook.MailItem
Dim MAddr As String, MSubj As String
MSubj = "Info da inviare" '<<<< Subject della mail
MAddr = "info@gecsi.it" '<<<< Destinatario
Set OLook = CreateObject("Outlook.Application")
Set MItem = OLook.createitem(0)
With MItem
.to = MAddr
.Subject = MSubj
.body = Range("A1").Value 'tuo ex Mbody
.send
End With
Application.Wait (Now + TimeValue("0:00:10"))
Set OLook = Nothing
Set MItem = Nothing
End Sub
Saluti e buon divertimento
