Missing updated property when using the delta query to track changes on users in Microsoft Graph API

Question

I need to track changes in any property of any user but it is not working for all properties. Here is what I'm doing:

1. I query the list of users using that request: https://graph.microsoft.com/v1.0/users/delta
2. I follow the link in @odata.nextLink then save the link in @odata.deltaLink.
3. I update the displayName property of a user in Office portal.
4. I follow the previously saved link. I can see the updated value of displayName among other basic properties of that user.

The problem is that if I do the same with the department property, the user is returned but the new department value is not included in the json.

In the documentation(https://developer.microsoft.com/en-us/graph/docs/concepts/delta_query_overview), it is said:

Updated instances are represented by their id with at least the properties that have been updated, but additional properties may be included.

which is not the case here.

I have also tested the jobTitle property which is not working at all, meaning that if I change its value, the delta link does not show any change at all. I suppose it is the same for many other properties..

Is there something I'm doing wrong?

Answer 1

I am able also to reproduce this issue. And event I specify select to display the department property, it still doesn't show in the changing result.

Based on the test, it seems that this property doesn't including in the track changes. If you have any idea or feedback about this REST, you can submit it from this link.
