Latest Message<\/th>\nTitle: Some users may have experienced devices intermittently entering a non-reporting state in Microsoft Defender for Endpoint <\/p>\n

User impact: Users may have experienced devices intermittently entering a non-reporting state in Microsoft Defender for Endpoint. <\/p>\n

More info: Some devices configured with the Telemetry Proxy Server registry may have intermittently experienced a non-reporting state, resulting in missing or delayed security telemetry in Microsoft Defender for Endpoint. Any detections that would have derived from that sensor data during the gap were not generated. Real-time endpoint protection, antivirus, device manageability, and device configuration\/identity all continued to function as expected.<\/p>\n

To attempt to identify devices that may still be impacted, they can search for devices in ‘No sensor data’: learn.microsoft.com\/defender-endpoint\/device-health-sensor-health-os#sensor-health–os-tab<\/a> <\/p>\n

Final status: We’ve identified that a service configuration update caused an issue in the sensor\u2019s dynamic component, leaving a stale proxy configuration that prevented telemetry uploads and resulted in impact. We’ve deployed a configuration fix to resolve the issue. However, affected devices require a restart or they should remove and re-add the proxy registry. <\/p>\n

Scope of impact: Impact was specific to some users utilizing devices that are configured with the Telemetry Proxy Server registry in Microsoft Defender for Endpoint. <\/p>\n

Start time: Wednesday, May 13, 2026, at 4:14 PM UTC <\/p>\n

End time: Wednesday, June 17, 2026, at 9:02 PM UTC <\/p>\n

Root cause: A service configuration update caused an issue in the sensor\u2019s dynamic component, leaving a stale proxy configuration that prevented telemetry uploads and resulted in impact. <\/p>\n

Next steps: We’re reviewing our configuration change procedures to help prevent this problem from happening again.<\/td>\n<\/tr>\n
