Hello,
We have detected the same issues on our side, by rerouting the mail
traffic to a lower volume server group it got temporarily solved for us.

Hello,
We have also detected this anomaly on some of our IPs. At the moment we
have solved it by relaing the queued messages from our other IPs and
they have been accepted regularly. This is why I thought the problem
was only ours.
Ciao

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
