Microsoft 365 Exchange Online E-Mail Probleme

End time: Wednesday, October 11, 2023 at 7:00 PM GMT+2

Preliminary root cause: A recent service update that was applied to a section of infrastructure responsible for enforcing IP address anti-spam rules contained a code issue, which was resulting in the delays with SMTP email delivery.

Next Steps:
- We're further reviewing the recent update to understand how the code issue was introduced and to understand what prevented it from being detected in our update testing and validation procedures, which will allow us to prevent similar issues in future updates.
