I think you're confused. APOP doesn't have anything to do with SASL
(which is what uses the AUTH command). There's a separate APOP command
for doing APOP authentication. It sounds like Outlook wants to do
SASL authentication (which I think there's some rudimentary support for
in qpopper, but I have no idea how well it works).
