Hi Andreas
We encounter the same thing. My guess is that issue is caused somewhere in Redmond. Hence I doubt there is anything we can do (except recommend using
proper mail hosting operators...)
Best regards

Hello all,
since a few hours we have problems with sending to Microsoft. We get hundreds of messages like in the subject with the reference to S77719. Also
colleagues from other companies in germany are seeing the same in their logs. All mails that are blocked here are from Microsoft customers, but they
are redirected through our servers.
Trying to unblock the IP e.g. via https://sender.office.com/ shows that the IPs
are not blocked.
Anybody have any idea?
Thanks a lot
Andreas
