Ensure that 'Users can create Microsoft 365 groups in Azure portals, API or PowerShell' is set to 'No'

低レベル 2手動レビューm365

説明

All users within a Microsoft Entra organization are permitted to create new Microsoft 365 groups and add members to those groups through the Azure portal, API, or PowerShell. Newly created groups also appear in the Access Panel for all other users. When the applicable group policy settings allow it, users can submit requests to join these groups. The recommended state is No. Restricting Microsoft 365 group creation to administrators only ensures that creation of Microsoft 365 groups is controlled by the administrator. Appropriate groups should be created and managed by the administrator and group creation rights should not be delegated to any other user.

Note: If a group with the above templateId doesn't exist this means the defaults are present and it would be advisable to use the UI to remediate, as this will automatically create the Group.Unified object with its defaults. Microsoft's documentation does cover using a POST request to build this using the API, however.
