wow the 365/outlook outage is still going, at some point the pending emails are going to start dropping from the delivery queues! At least from my end when I/bgp.tools tries to deliver email to there I either get a TCP timeout or something like a:
remote smtp server sent unexpected response status code: got 451, expected 2xx, transient: 451 4.3.2 Temporary server error. Please try again later ATTR2 [xxx.ausprd01.prod.outlook.com 2026-11-13T05:25:11.271Z xxx]

@benjojo FYI... NHS.net Mail runs on Office365 (certainly that was the plan about a decade ago, it was on a custom Outlook install before that (and a Mirrorpoint one before that, to be fair, it may not even exist now). NHS.net was the only mail platform allowed for the NHS Primary Cancer Care programme
If emails goes missing, people can literally die (delays of weeks can be enough to halve your chances of survival in some cases). Ask me how I know that (actually don't, it's not nice).
