alt Hacker NewsRequiring DMARC may be good, but Outlook's approach is awful.
I was working for Microsoft when outlook.com launched and got a good email address that was my primary for more than a decade.
I had so many issues with things getting silently dropped with no recourse (2FA codes, account recovery mails, etc.) on so many sites that I finally gave up, reversed the stream, and had Outlook forward to GMail instead of vice versa. A few months after that, I realized that all my Outlook got was an enormous volume (hundreds of day) a spam and that all legitimate mail was going to my other accounts, so I turned it off entirely and haven't read that mailbox in over a year.

This is not unique to Microsoft and really the source's problem — they did something to get blocked in the first place.
Add in the fact that you're almost certainly not the only one impacted, and that they have no interest in fixing it, it screams incompetence on the source's part.
Been there, done that, good luck explaining the problem to the app's first-level support in the Philippines because it's not in their script.

Till the day GMail hits you with the "We couldn't verify it's you" bullshit and locks you out of your account forever. Good luck getting support from Google, the word is not in their lexicon.
