Current status: We're continuing to apply the targeted authentication component fix across the remaining affected infrastructure where necessary. Service telemetry continues to indicate recovery, with availability increasing across previously impacted scenarios as remediation progresses. We're validating that authentication, connectivity and search operations are returning to expected service levels while monitoring for any residual impact and confirming that the remediation is delivering broad mitigation across affected Exchange Online scenarios. As recovery signals continue to trend positively, we're maintaining extended monitoring across affected service workflows to ensure improvements are sustained.
Scope of impact: Users attempting to perform any of the outlined impact scenarios may be affected by this event.
Root cause: An issue within a core authentication configuration used by multiple Microsoft 365 services is resulting in impact.
