How to use this result

Use this report to identify managed-device records where Intune returns a blank UserId.

When this helps

  • Review shared, kiosk, stale or incompletely associated devices that have no assigned user in the managed-device record.
  • Find records that need ownership verification before migration or cleanup.

How to read the result

  • A blank UserId means this Intune managed-device record has no assigned user identifier in the returned data.
  • That does not automatically mean the device is unused, unowned or incorrectly configured; shared and userless scenarios can be intentional.

Things to check

  • UserPrincipalName can also be blank in legitimate device scenarios.
  • Confirm enrollment model, device purpose and asset ownership before assigning or removing associations.

What to do next: Check the device's enrollment scenario and business owner before deciding whether the missing user association is expected.
