Betroffen
This issue affected some admins attempting to review Service health or Message center postings in the Microsoft 365 admin center or see new activities in the “What’s new” tab in the Microsoft Teams admin center.
Ursache
A recent service update introduced a misconfiguration which caused the Service Health and Communications API to return authentication errors, resulting in impact.
Next steps:
- We're analyzing the offending service update to determine why the potential for impact wasn't caught during our internal update testing and validation phases. This further analysis will help us to improve our update implementation processes moving forward to ensure similar impact scenarios don't occur in the future.
This is the final update for the event.

We've completed our monitoring period and validated that the rollback of the service update containing the misconfiguration successfully remediated impact.
