Exchange Online mit Störung (30./31. August 2023)

Störungstage bei Microsofts Cloud. Nachdem Blog-Leser Andreas mich gestern bereits über eine Teams-Störung informierte (siehe Microsoft Teams gestört (30.8.2023)) geht der Reigen weiter. Bereits seit dem 30. August 2023 gibt es wohl auch Störungen bei Exchange Online, die aktuell zum 31. noch anhalten, wie mir Andreas per Mail mitteilte (danke dafür).

7 Antworten zu Exchange Online mit Störung (30./31. August 2023)

  1. Blubmann sagt:

    Mal so berechtigte Frage. Kann es ein, dass die Störungen in den letzten Monaten deutlich gestiegen sind oder wird einfach nur mehr darüber berichtet?

    • Daniel A. sagt:

      Kommt mir auch so vor. Wir verwenden zwar nicht Exchange Online, haben aber M365 für Office und Teams. Daher bekommen wir auch immer die "Health Notification" Emails, und da ist in letzter Zeit ständig mindestens ein Dienst betroffen, der in irgendeiner Form nicht oder nur eingeschränkt erreichbar ist. In den meisten Fällen ist das innerhalb weniger Stunden bis 1 Tag erledigt, aber halt auch nicht immer. Ist halt doof, wenn man darauf angewiesen ist. Bin dann immer froh, dass wir den Exchange noch lokal haben.
      Von den "kleineren" Fehlern, die teilweise seit Monaten im Admincenter angezeigt werden, rede ich dabei nicht mal.

    • JohnRipper sagt:

      MS gibt zu den 365 Produkten mE ziemlich kleinteilige Meldungen heraus. Ich bekomme auch oft sehr viele angezeigt, signifikant betroffen war ich bisher selten, da oft auch nicht die gesamte Infrastruktur betroffen ist.

      Dadurch dass jedoch viel umgekrempelt wird, gibt es aber auch mehr Fehler.

      Und seit den größeren Ausfällen wird auch mehr berichtet.

      Wobei man hier im Blog auch vom einzelnen Personen abhängig ist, die Meldungen weiterleiten, was sie früher vllt auch nicht getan haben bzw. manchmal auch nicht tun.

      Insofern gibt es eine eindeutige Antwort vermutlich nicht.

    Man bekommt sowieso viel zu viel blödsinnige Mails, danke M$ für diese Ausfälle :-)

    Gefühlt hatte Intune heute morgen auch n bissel Schluck auf.

    Habe mehrere Rechner gesehen die beim syncen einen 400er Error bekommen haben. hat sich aber ab ca 10 Uhr wieder normalisiert

  4. pau1 sagt:

    Früher gab es mal so etwas wie "Ping my Server".
    Geht das nicht mehr bei Microsoft 365, weil die alles durch HTTPS oder VPN prügeln ?

    Es ergibt sich doch irgendwie der Eindruck, als wären die Störungen sehr oft national begrenzt.
    D.h. seitens MS wird man mit negativen Status Meldungen zugemüllt, die für die EU Null relevant sind, seine relevanten Probleme erfährt man aber erst von den eigenen Usern, wenn deren Langmut erschöpft ist, weil die Status Meldungen von MS auch erst dann kommen.
    Nebenbei könnte man so ja feststellen, wie hoch die Verfügbarkeit der MS Dienste ist und entsprechend auf den Preis drücken..
