It appears to us that the delay only affects EU SMTP servers. US SMTP servers delivery is fine.

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?
