I believe Microsoft is working with spammers. I have a public facing Outlook email for a specific reason. Naturally, I get a lot of junk mail in that account. Whenever I create a "rule" to filter out junk, within a very short period of time, sometimes less than an hour, spam appears set to go around that filter.

For example, I get some spam looking to get me to sign up for Obamacare plans. I create a new rule that says all emails with the text "Obamacare" in the subject go to the junk folder.

Later that day, I will get an email with the subject "O.b.a.m.a.c.a.r.e." However, that often doesn't happen when I don't create the filter.

Many such examples.

Of course, the email comes from [email protected] so blocking the sender does no good.
