My work office365 mailbox is unusable. Normal mails ends up in spam or quarantine, or gets delivered with a very large delay.

TBF that might not be MS's fault. My work office365 mailbox is similar, but it was about the same before we moved to office365 due to additional filtering our IT does in the name of security.

The fact that Microsoft doesn't just whitelist their own domains speaks to their commitment to strict security measures and good engineering culture. Special cases aren't special enough to break the rules.

On the other hand, `notify.trafficmanager.net.`, the domain name used for Edge push notifications through Azure Traffic Manager, currently points to `notify1.ontario.ca.` with a CNAME record. This resulted in an Edge push notification outage a couple weeks ago, but they never fully fixed it. Push notifications are working again because they use subdomains of `notify.trafficmanager.net`, but `notify.trafficmanager.net` itself is simultaneously used by one of their Azure customers--and they seemingly have no idea.

In other words: `*.notify.trafficmanager.net` is special-cased, and this has caused problems.

They can and do whitelist all sorts of things for special cases. Microsoft is good at what they do, but they are a pragmatic company.

My guess here is that some junk folder routing is on client side, or the user flagged junky email from the same infrastructure as junk. Or, O365 tweaked some settings to address the issues with spammers using Outlook infrastructure that bypasses spam controls.

Earlier quoted context omitted.

>speaks to their commitment to strict security measures and good engineering culture Does it really or does it just mean that nobody cared enough to do it for whatever reason?

I'm sure the Azure people are aware and annoyed. I appreciate that the security people are holding the line.

Or Microsoft are just terrible at classifying spam

It would seem they actually do whitelist some of their own stuff - specifically those weird "Microsoft Viva" emails that Outlook users get. A year or two ago, I did get Outlook to classify those emails as "Junk" automatically, by repeatedly reporting them - but then something changed, and after that they never were marked as "junk" again - no matter how often I do report them.

I've never gotten a Microsoft Viva email across a couple of O365 accounts but none of the orgs ever set up Viva to my knowledge. If it's something your org set up it'd make sense it could break the rules, otherwise dunno.
