Verified with Microsoft 365/Office 5568.1000 — updated on September 4, 2026
Supported on: At least Windows Server 2016, Windows 10
Path in the GPO console
User Configuration\Administrative Templates\Microsoft Office 2016\Security Settings\Trust Center\Application Guard Description
The policy allows you to control whether Office apps using Application Guard can access the user's camera and microphone if they're enabled on the user's device. Important: A compromised Application Guard container could bypass camera and microphone permissions and access the camera and microphone without the user’s knowledge. To prevent unauthorized access, we recommend that the camera and microphone be turned off on the user’s device when they aren’t needed. If you enable this policy setting, Office apps using Application Guard won't be able to access the camera and microphone on the user’s device. If you disable or don't configure this policy setting, Office apps using Application Guard will be able to access the camera and microphone on the user’s device. Note: This policy setting only applies to Microsoft 365 Apps for enterprise.
