that operators add CNAMEs/As/AAAAs for those exact hostnames?
If you mean its "auto account setup" feature, not its horrid autodiscover
protocol, then yes but with caveats: if there are multiple possible
configurations (e.g. pop/imap, tls/clear, smtp/submission) then I don't
trust Outlook's preferences to be the right ones to document. The choice
of hostnames and ports to probe is more likely to be reasonable.
I tried to find some documentation on Microsoft's site describing what
probes Outlook performs, but annoyingly I failed.
