oOutlook = GETOBJECT(,"Outlook.Application")
   oNameSpace= oOutlook.GetNamespace("MAPI")
   oFolder = oNameSpace.GetDefaultfolder(4)     && Go to Outbox, folder 4
   oSend = oFolder.Items(1).Send                && Send waiting items

>I am sending e-mail messages in MS OutLook through Automation and OutLook is placing the messages in the OutBox, I want to know how to force Outlook to actually send the messages as if I clicked the send/receive button.
