Title: Some users may not be receiving email messages in all Exchange Online connection methods
User impact: Users may not be receiving email messages in all Exchange Online connection methods.
Current status: Due to an unexpected conflict, we were unable to move email traffic away from this unhealthy set of infrastructure. We reviewed the network logs to identify an alternate solution to remediate impact and discovered an authentication problem that may be contributing to this issue. We're investigating the configuration of the affected infrastructure to better understand this authentication issue, potentially allowing us to create a strategy that remediates impact.
Scope of impact: Some users expecting to receive email in any Exchange Online connection method are impacted.
Root cause: A subset of infrastructure that routes the affected email isn't processing data as expected, resulting in impact.

Title: Some users may not be receiving email messages in all Exchange Online connection methods
User impact: Users may have not been receiving email messages in all Exchange Online connection methods.
Final status: After our review the configuration of the affected infrastructure, we've developed an expedited fix target that replaces the affected piece of infrastructure that routes the affected email messages and have confirmed through telemetry that impact has been remediated.
Scope of impact: Some users expecting to receive email messages in any Exchange Online connection method were impacted.
Start time: Tuesday, November 28, 2023, at 5:20 PM UTC
End time: Wednesday, November 29, 2023, at 4:40 AM UTC
Root cause: A subset of infrastructure that routes the affected email wasn't processing data as expected, resulting in impact.
Next steps:
– We're continuing to investigate why the subset of infrastructure that routes the affected email wasn't processing data as expected to prevent similar instances in the future.This is the final update for the event.

Die Kurzfassung: Nach Überprüfung der Konfiguration der betroffenen Infrastruktur , in der E-Mails nicht weiter geleitet wurden, haben die Microsoft Techniker einen Fix entwickelt. Dieser sorgte dafür, das der betroffene Teil der Infrastruktur, der die betroffenen E-Mail-Nachrichten weiterleiten soll, ersetzt wird. Durch Telemetrie wurde bestätigt, dass die Auswirkungen behoben sind.

Aktuell gerade keine Probleme.
Mir ist aber unklar ob es ein Problem beim Zugriff auf das Postfach sein soll oder bei der Mailzustellung in selbiges.
Es ist mehrfach von "email traffic" die Rede, also wohl die Bewegung von Mails zwischen den Microsoft-Servern.
Wenn man in größeren geclusterten Systemen Mails bewegt, müssen die Hosts sich in gewissen Grenzen gegenseitig kennen und vertrauen (bei einem einzelnen lokalen System würde man "127.0.0.1" andere Rechte geben).
Wie Microsoft das macht (ob auch per IP-Listen oder einen Login- bzw. Token-Mechanismus weiß ich nicht), aber wenn das nicht funktioniert, werden z.B. die gerade vom eigenen Virenscanner geprüften Mails oder die ggf. vom Autoresponder generierten in die selbe Schublade geworfen wie frisch aus dem Internet empfangene.
Hier funktioniert beides. Zugriff auf das Postfach über Web. Also auch der Empfang von Emails
Exchange Online ist gestört wird langsam zum Evergreen.
