Those "false positives" are clearly made on purpose to boycott independent mail providers, it doesn't matter if an IP sends less than 10 emails per day on average during years and has never been black listed in any public list, it will stay on Microsoft blacklist forever and there is no easy/cheap way to remove it. And of course, they will never tell you WHY they have blacklisted you in the first place.
Yes, and explicitly so — see the reply from Microsoft Agent 2 years ago on answers.microsoft.com https://answers.microsoft.com/en-us/outlook_com/forum/all/microsoft-repeatedly-blocking-ip-and-now-refusuing/c1855c68-a7a5-41fd-a4f3-3b1ee7555748
"IPs not previously used to send email typically don't have any reputation built up in Outlook.com systems. As a result, emails from new IPs are more likely to experience deliverability issues. Once the IP has built a reputation for not sending spam, Outlook.com will typically allow for a better email delivery experience. However, since you've already tried submitting a delist request, it should rectify the issue."
In other words, for their service/business small users must (periodically) fight for relevance (or fringes don't matter, whichever you prefer).
That's one reason I continue to advise anyone against using Microsoft services.
And I use my Microsoft work email just as a dumb transit. I download then both the Inbox and Junk folder contents and filter them on my notebook with Spamassassin and other rules.
