Thanks!
Some additional context:
- I checked online and they do have this email address listed on their pages
- This affected 2 separate domains served by Microsoft
- I sent them an inquiry email now from my @gmail.com and no bounce was returned so far
EDIT: Also gmail got the error response, so I guess it's really up to the outlook server these unrelated entities use...
