User impact: Admins may have been unable to view up-to-date Exchange Online reports from April 2, 2023, or later.

More info: Any aggregated Exchange Online Protection report from the security portals, Defender portals, and the Exchange admin center (EAC) were impacted.

Final status: We’ve identified that a recently introduced feature update contained a configuration that prevented the binary files required to populate aggregated Exchange Online Protection reports from processing as expected, resulting in impact. We’ve disabled the offending feature update in the affected databases to allow these files to process and confirmed that impact is remediated after monitoring the affected environment.

Scope of impact: This issue may have affected any admin attempting to view up-to-date aggregated Exchange Online Protection reports from the security portals, Defender portals, or the EAC.

Start time: Monday, April 3, 2023, at 5:00 PM UTC

Root cause: A recently introduced feature update contained a configuration that prevented the binary files required to populate the impacted reports from processing as expected, resulting in impact.

Next steps:
– We’re assessing why impact wasn’t caught during the feature update testing phase so that we can improve our pre-deployment testing procedures.

This is the final update for the event.
