Well, thanks. I managed to write this code and it works:
import winim/com
var obj = CreateObject("Outlook.Application")
var olMailItem = 0x0
var newMail = obj.CreateItem(olMailItem)
newMail.Subject = "test"
newMail.Body = "Bodytest"
newMail.display()
RunI'll leave it here as somebody might need it in the future.
