Microsoft Edge management service in Microsoft 365 Admin Center lets you set policy and manage users through a Microsoft Edge focused cloud-based management experience. This policy lets you specify an enrollment token that's used to register with Microsoft Edge management service and deploy the associated policies. The user must be signed into Microsoft Edge with a valid work or school account otherwise Microsoft Edge will not download the policy. If you enable this policy, Microsoft Edge will attempt to use the specified enrollment token to register with the Microsoft Edge management service and download the published policy. If you disable or don't configure this policy, Microsoft Edge will not attempt to connect to the Microsoft Edge management service.
