Latest Message<\/th>\nTitle: Some admins may experience a gap in security telemetry data and alerts in Microsoft Defender for Endpoint and Identity <\/p>\n

User impact: Admins may experience a gap in security telemetry data and alerts in Microsoft Defender for Endpoint and Identity. <\/p>\n

More info: Impacted admins may experience a point-in-time gap of approximately 30 minutes in security telemetry data for Microsoft Defender for Endpoint and Microsoft Defender for Identity (V3 clients) when viewing information in the Microsoft Defender portal and Microsoft Sentinel, as the affected data wasn\u2019t ingested. <\/p>\n

Current status: Our efforts to backfill the telemetry data gap from the impact window is progressing. We expect impact to be fully remediated and the backfill of telemetry data to be complete by our next scheduled update.<\/p>\n

Scope of impact: Some admins relying on security telemetry reporting in Microsoft Defender for Endpoint and Microsoft Defender for Identity (V3 clients) may be impacted. This information may be updated as our investigation continues. <\/p>\n

Start time: Wednesday, May 20, 2026, at 7:30 AM UTC <\/p>\n

Root cause: An authentication component misconfiguration is causing authentication issues within a core part of the Microsoft Defender for Endpoint and Microsoft Defender for Identity services, resulting in telemetry data for a 30-minute window not being ingested. <\/p>\n
