Licence: Microsoft Intune.
Endpoint:
GET /v1.0/deviceManagement/managedDevices (freeStorageSpaceInBytes, totalStorageSpaceInBytes, enrolledDateTime)
Storage is reported by the device at check-in; some platforms (e.g. Android work profile) report none.
If a permission is missing, this report shows a red load error with the Graph status code — not an empty table.
