> This is fairly normal in today’s world of email providers, and one of the reasons it can be painful to manage your own SMTP server, right? Yes. Silently discarded e-mail is the worst thing that can happen because you can't detected it as a sender. Your message reaching the spam folder is bad, but not as bad as getting silently discarded. The best among the bad options is probably getting rejected with the SMTP return code 550 along with instructions how to delist in the return message.

If you are running a business and have customers having emails that are silently being dropped, adding a "verify your email address" page in your process is probably a good step to have anyway.

  Why exactly? Would Microsoft's internal spam filter likely consider that spammers often don't provide that page so you would stand out?

    If they're consistently dropping mail, the user stays unverified. But a verification page is practically mandatory anyway for all sorts of reasons, not least checking the user hasn't mistyped their email.

    If you’re being silently discarded you likely have terrible reputation, and requiring verification will help to fix that.

      It's increasing becoming the case that "terrible reputation" now includes the low reputation self hosters who don't have enough volume to even use the tools Google and Microsoft offer. Google's Postmaster tools all show "No data to display at this time. Please come back later. Postmaster Tools requires that your domain satisfies certain conditions before data is visible for this chart." Microsoft's Safe Network Data Service shows *"No data for specified IPs on this date" for every day.

Don't worry they do that as well. First VPS I got had been completely blacklisted at the provider level and they were refusing everything with 550. Support didn't reply either.
