Latest Message<\/th>\nTitle: Some admins may experience delays in Microsoft Defender for Endpoint detections <\/p>\n

User impact: Admins may experience delays in Microsoft Defender for Endpoint detections. <\/p>\n

More info: Affected admins may experience delays in receiving Microsoft Defender for Endpoint detections in the Microsoft 365 Defender portal and Microsoft Sentinel. <\/p>\n

Current status: We’ve implemented performance optimizations to assist with restoring the affected section of the detection processing infrastructure that was causing delays, and we\u2019ve validated from our service monitors that users are now receiving new Microsoft Defender for Endpoint detections in the Microsoft 365 Defender portal and Microsoft Sentinel. We’re processing the backlog of affected Microsoft Defender for Endpoint detections, and we aim to provide a timeline to remediation by our next scheduled update. <\/p>\n

Scope of impact: Some admins expecting to receive Microsoft Defender for Endpoint detections in the Microsoft 365 Defender portal and Microsoft Sentinel detections may be impacted. This information may be updated as our investigation continues. <\/p>\n

Start time: Wednesday, August 26, 2026, at 12:50 PM UTC <\/p>\n

Root cause: A section of the detection processing infrastructure that is causing delays in the detections pipeline. <\/p>\n

Next update by: Thursday, August 27, 2026, at 5:00 PM UTC<\/td>\n<\/tr>\n
