Latest Message<\/th>\nTitle: Admins may not be receiving Microsoft Defender for Office 365 alerts in Microsoft Defender XDR<\/p>\n

User impact: Admins may not have been receiving Microsoft Defender for Office 365 alerts in Microsoft Defender XDR.<\/p>\n

Final status: Following the deployment of our fix and monitoring a queue of backlogged alerts that required processing, our internal telemetry has verified that the impact has been remediated.<\/p>\n

Scope of impact: Impact was specific to some users who were served through the affected infrastructure.<\/p>\n

Start time: Monday, April 14, 2025, at 8:15 AM UTC<\/p>\n

End time: Monday, April 14, 2025, at 5:20 PM UTC<\/p>\n

Root cause: A recent service update that intended to improve event hubs for service infrastructure had caused a subset of infrastructure that helps facilitate Microsoft Defender for Office 365 alerts to drop below our manageable service performance thresholds, resulting in impact.<\/p>\n

Next steps:
– We’re further analyzing the recent service update to better understand the problems that it produced and so we can help isolate similar issues during our pre-deployment testing and validation processes. <\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
