Individual request to the Managed device returns wrong user information

Question

Managed Intune device resource has some user information fields: userId, userPrincipalName, userDisplayName.

Request to the devices list https://learn.microsoft.com/en-us/graph/api/intune-devices-manageddevice-list?view=graph-rest-1.0&viewFallbackFrom=graph-rest-beta
returns a correct actual Primary User data (at least now, about 1-2 years ago it was not accurate for example after primary user changing)

Request to an individual device https://learn.microsoft.com/en-us/graph/api/intune-devices-manageddevice-get?view=graph-rest-beta returns a wrong Primary User information for several devices (but I have actual PU data for these devices in the List response).

Even for one device (I set primary user a long time ago) UserId is returned correctly while UserPrincipalName and UserDisplayName are null! (see screen below)

What is happening here? Can this issue be fixed please?

P.S. I know that correct primary user data can be loaded from another query
GET /beta/deviceManagement/managedDevices/{managedDeviceId}/users
But it would be nice if Individual request will return a correct data, like the list request does now.

And we avoid using additional requests for each device / primary user due to query limits, it is very inconvenient and need much time when there is a large amount of devices.

Answer 1

@Katie Parfinenko, Thanks for posting in Q&A. From your description, it seems the UserPrincipalNam is not correct or none after we change the primary user of one managed device. It affects some devices.

Based on my checking in my environment, I find it displays correct after I change primary user.

So I suggest open case to check in the background to see if there's any synced issue there.

Thanks for your understanding.
