Well that depends, we use both CDO and Outlook, when we need a record that the e-mail was sent successfully and be able to proof it (for example our purchasing system) then we use Outlook, but when we need to send e-mails 24/7 non-stop, then Outlook sucks, as after a few days it always died on us; so in that case we use CDO, and the same program (it actually has a checkbox to allow us to select the delivering method) it can run for months un-attended if using CDO.
