Default idle detection setting

Computer and userIntune-readyDefaultIdleDetectionSetting

Supported on Microsoft Edge version 145, Windows 7 or later

155.0.4283.62

What it does

Setting this policy to 1 - AllowIdleDetection allows websites to use the Idle Detection API without requesting user permission. Setting this policy to 2 - BlockIdleDetection prevents websites from using the Idle Detection API. Setting this policy to 3 - AskIdleDetection requires websites to request user permission each time before using the Idle Detection API. If you do not configure this policy, users can decide whether to allow the Idle Detection API and can change this setting themselves. Policy options mapping: * AllowIdleDetection (1) = Allow sites to detect idle state without asking the user * BlockIdleDetection (2) = Do not allow any site to detect the user's idle state * AskIdleDetection (3) = Ask every time a site wants to detect the user's idle state Use the preceding information when configuring this policy.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: DefaultIdleDetectionSetting
