Configure extended cloud check

ComputerNative Intune settingMpEngine_MpBafsExtendedTimeout

Supported on At least Windows Server 2016, Windows 10

23H2 · 1.0

What it does

This feature allows Microsoft Defender Antivirus to block a suspicious file for up to 60 seconds, and scan it in the cloud to make sure it's safe. The typical cloud check timeout is 10 seconds. To enable the extended cloud check feature, specify the extended time in seconds, up to an additional 50 seconds. For example, if the desired timeout is 60 seconds, specify 50 seconds in this setting, which will enable the extended cloud check feature, and will raise the total time to 60 seconds. Note: This feature depends on three other MAPS settings - "Configure the 'Block at First Sight' feature; "Join Microsoft MAPS"; "Send file samples when further analysis is required" all need to be enabled.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.

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.
