[English]Zum 5. Juni 2023 hat es bei Microsofts Exchange Online wohl eine massivere Störung gegeben. Administratoren kamen nicht mehr ins Admin-Center und Outlook konnte im Web nicht mehr erreicht werden. Ein Nutzer hat mich auf diese Störung hingewiesen, die kurz vor 16:00 Uhr deutscher Zeit begann, inzwischen (18:40 Uhr) aber wohl weitgehend behoben ist. Microsoft hat die Störung inzwischen bestätigt. Ergänzung: Inzwischen behauptet die pro-russische Hackergruppe Anonymous Sudan für die Störung (per DDoS) verantwortlich zu sein.

Eine Lesermeldung
Ein Blog-Leser hat sich kurz vor 18:00 Uhr bei mir per E-Mail gemeldet und berichtete über die aufgetretene Stärung bei Exchange Online. Laut Leser gab es wohl "einen richtig großen Exchange Online Ausfall". Der Leser hat mir folgenden Screenshot des Service Heath Dashboard mitgeschickt, der die Statusseite zeigt. Dazu schrieb der Leser:
Ist bei uns trotz Azure Location West (Holland/Irland) bemerkbar, dass Outlook kein Connect bekommt bzw. Outlook Online nur Fragmentiert was anzeigt. Mal gehts, mal gehts nicht, dann gehts dann wieder nicht :-)
Mal schauen ob es noch mehr werden wie 100 …
Im Admin Center schaut das ganze aus wie ein Alarmstufe Rot auf der Enterprise :-D

Auf reddit.com gibt es ebenfalls diesen Thread, wo jemand gegen 16:00 Uhr nachfragt, ob es eine Störung gäbe. Dort bestätigen weitere Betroffene den Ausfall. Ich habe mal den downdetector (bzw. die deutsche Seite allestoerungen.de) befragt und bekam diesen Ausfall quasi bestätigt – es gibt einen Peak bei den Störungsmeldungen.
Microsoft bestätigt den Ausfall
Auf Twitter gibt es von Microsoft inzwischen die Bestätigung zu einem Problem. Am 5. Juni 2023 schreibt Microsoft365-Status gegen 16:47 Uhr deutscher Zeit folgendes:
We're investigating an issue with accessing Outlook on the web. Further details can be found under EX571516 in the admin center.
Später wurde das dann folgendermaßen ergänzt:
We're reviewing our networking systems and recent updates in an effort to identify the underlying root cause of the issue. Additional information can be found in the admin center under EX571516.
Und vor 49 Minuten hieß es:

We've identified downstream impact for Microsoft Teams, SharePoint Online and OneDrive for Business. We're providing full impact details and updates for those services via MO571683. Updates pertaining to Exchange and Outlook on the web will continue to be provided via EX571516.
We've halted an ongoing deployment and are monitoring services to see if that provides relief to the environment. Further information can be found in the admin center under EX571516 and MO571683.
Es gibt also eine Störung, die den Zugriff auf Outlook im Web verhindert. Das hat auch Auswirkungen auf Microsoft Teams, SharePoint Online und OneDrive for Business identifiziert. Microsoft will vollständige Details zu den Auswirkungen und Updates für diese Dienste über MO571683 bereitstellen. Updates für Exchange und Outlook im Web werden weiterhin über EX571516 bereitgestellt. Inzwischen hat Microsoft in nachfolgender Meldung mitgeteilt, dass eine laufende Bereitstellung gestoppt wurde.
We've reverted the update and telemetry shows service improvement. We're continuing to monitor the service to ensure recovery and performing actions to address any residual impact. Further information can be found under EX571516 and MO571683 in the admin center.
Aktuell überwacht Microsoft die Dienste und hofft, dass die Störung langsam abklingt. War jemand von euch betroffen? Falls jemand Zugriff auf die Statusmeldungen im Admin-Center hat, kann er diese ja hier posten.
Pro-russische Hacktivisten verantwortlich?
Ergänzung: Inzwischen behauptet die pro-russische Hackergruppe Anonymous Sudan für die Störung verantwortlich zu sein. Nachfolgender Tweet verweist auf diesen Beitrag, wo Auszüge der Stellungnahmen dieser Hacktivisten zu finden sind. Die Hacktivisten geben an, Microsofts Server per DDoS-Angriff überlastet zu haben. Wie belastbar das ist, kann ich nicht beurteilen.

End time: Monday, June 5, 2023, at 5:13 PM UTC
Preliminary root cause: A recent update, intended to add additional resilliencies against downstream request remaining in a hanging state, inadvertently caused impact.
Next steps:
– We're reviewing dump files gathered from impacted components during the incident to better understand why impact occurred.
– We're investigating to content of the update to identify the underlying root cause.We'll publish a Post-Incident report within five business days.
Published Time: 05.06.2023 19:07:56
Telemetry indicates that service availability is at approximately 99.9% across the service. We're continuing to isolate a small number of components which remain in an unhealthy state and are performing targeted restarts to remediate the residual impact.

Keinerlei Störung bemerkt
„MO572252, impacted service: Microsoft 365 suite, impacted feature: Portal, current status is: Service degradation" folgt auf dem Fuße.
Hat auch Bezug zu der Exchange Störung EX571516.
Im Admin Center geht aktuell fast nichts bzw. wenn dann nur mit sehr langen Ladezeiten.
iOS/iPad User berichten von Problemen beim Mailversand.
Edit:
AlleStörungen zeigt auch wieder gestiegene Problemmeldungen.
Hier in CH klemmte es auch. Outlook Preview ohne ost ging gar nicht mehr. Exchange Admin Panel warf eine API FM und Outlook Online ne 503

Scope of impact: Users routed through the affected infrastructure are affected by this issue, however, impact can vary depending on where users are hosted.
Weiß nicht, obs direkt mit dieser Störung zu tun hatte, aber die Desktop-Version von Outlook hat gestern gegen 15:45 mein Profil gekillt (beschädigte OST), ich musste heute morgen alles neu aufsetzen. Was jetzt immer noch klemmt: es werden keine älteren Mails in unseren zahlreichen Gruppen angezeigt (obwohl der Exchange-Cache-Modus auf "alle" eingestellt ist), Online klappts aber.
Eigentlich ist das eine Client Einstellung.
Trotzdem gab es merkwürdiges Verhalten, von keine Probleme, über langsam aber funktionsfähig bis Totalausfall.
Am besten nochmal das Profil, inkl. *.OST löschen und nochmal Versuchen.
Bei mir gehen seit heute morgen bei einzelnen Usern die Backups auf die Bretter…
Kann es sein, dass schon wieder Störungen auftreten. Mein Outlook hängt in "keine Rückmeldung" wenn es abrufen will…
Kann ich bestätigen, seit heute 1000 (bis ca. 1030) war outlook.office.com nicht erreichbar sowie Einschränkungen im Outlookclient, die Suchfunktion funktionierte nicht. Empfangen / versenden ist laut vorliegendem Mailproxy aber erfolgreich.
Hier bei uns sind auch noch starke Einschränkungen zu spüren: OWA lädt teils gar nicht, ganz zu schweigen davon, dass keine Mails abgerufen oder gesendet werden könnten. Die Desktop-App von Outlook funktioniert noch am besten, hier berichten manche User von weniger starken Einschränkungen.
Please fix this MS
