None of the big providers send DMARC messages. Google doesn't. Microsoft doesn't. The only DMARC messages I've ever gotten were from Yahoo and mail.ru. Google/Microsoft don't send DMARC reports because it would make it easier for spammers to know they had gotten past those filters. It's easier to just drop everything they don't like silently. It's why e-mail is terribly unreliable today (much more reliable if you DO NOT use Microsoft or Google).

I regularily receive dmarc reports from Google (every day) and yahoo for instance. Not sure I've ever received any dmarc report from hotmail though. And email is pretty reliable with Google. It is a disaster with hotmail: you have to send a big number of emails to have a chance that hotmail treats your email as non spam. They put your self hosted emails in the spam folder of your regular contacts, and the fact that they respond to your emails and systematically mark them as non spam is an irrelevant detail for them.

  I've got Hotmail aggregate reports up through 2017 (sent from microsoft.com though).

    Oh yes, this is right, me too. Last report on 2017-10-31.

Google/Microsoft don't send DMARC reports because it would make it easier for spammers to know they had gotten past those filters. Is that a recent thing? I was getting DMARC reports from both Google and Yahoo as late as April this year. Around then I pared down my Sonic account and they ate a bunch of stuff that I was too lazy to setup again including DMARC. While Google and Yahoo make up most of the reports I got this year, I also see some from Microsoft and AOL from 2017. 163 (China) used to send out reports too.

  Aggregate or forensic? I’m not sure I’ve ever seen a forensic report.

    Aggregate or forensic? I’m not sure I’ve ever seen a forensic report. Both. In looking at my mailbox I see some forensic reports from 163 and aggregate reports from everyone I mentioned plus Comcast, Emailsrvr, XS4ALL, and QQ. I don't remember if I eventually turned off forensic reporting, but I do remember that LinkedIn and Facebook were particularly strong proponents of DMARC (and both were really good about accidentally load testing our infrastructure). Oh and one very large provider that actually gave us unredacted messages. Boy am I glad GDPR is a thing these days.
