Störung bei Exchange Online (14.12.2021)

Kurze Meldung zu Microsoft Exchange Online. Gestern gab es wohl Störungen, die Nutzer von Exchange Online betrafen. Mails, die über Exchange Online verschickt werden sollten, werden verzögert verschickt oder bleiben als Entwurf bzw. zu Senden hängen.

Blog-Leser Andread P. hat mir die Nacht folgende Informationen per Mail zugeschickt – jemand betroffen:

Vorfall: EX305387, betroffener Dienst: Exchange Online, betroffenes Feature: delivery, aktueller Status: Service degradation

Title: Some users' Exchange Online outgoing messages are delayed or stuck in the Drafts or Sent Items folder after sending
User Impact: Users' Exchange Online outgoing messages are delayed or stuck in the Drafts or Sent Items folder after sending.
More info: Email that is stuck in the Drafts folder as well as some messages showing in the Sent folder aren't received by the recipient.

Current status: We've identified that a recent routing configuration change on a portion of infrastructure that facilitates message submission resulted in an abnormally large number of messages routing through the affected infrastructure and queueing for delivery We're correcting the routing configuration change problem to mitigate this issue. We expect that this will complete by our next update; however, additional time will be required for all queued messages to be processed.

Scope of impact: This issue affects some users sending email through Exchange Online that are served through the affected infrastructure.
