-Some users may also experience delayed or failed file opening, Office policy-label retrieval, OneDrive synchronisation, mobile camera upload, and video playback.
-Users may see partial page failures, missing or stale content, repeated retries, and operation timeouts rather than a complete platform outage.

Microsoft 365 Admin Center:

Current status: Reapplying the targeted authentication component fix and restarting affected infrastructure segments has led to measurable progress. We're observing gradual improvements within telemetry data related to search functionality across the remaining affected infrastructure, and we're continuing this remediation effort across additional infrastructure segments while closely monitoring service health telemetry to ensure we're progressing towards a broader recovery.

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.
