You said DMARC does not prevent email forgery. I simply corrected you on that and explained what DMARC does.
Setting a DMARC policy that allows unsigned emails is easier than configuring DMARC signing including key management. It's just adding a DNS record. Although large senders should of course do DKIM and it's not that hard either
But I'm not arguing with you about whatever Outlook did.
