When you check Device compliance in order to see what users logged on in a device, and you ran a query in Graph with the property -usersloggedon (beta version), the information usually doesn't match.
Most of the time there are more users in Device compliance than in Graph, and I wonder why. Does Microsoft Graph (beta) -usersloggedon property store info for a specific period of time?
Property -usersloggedon is not available in v1.0 of Graph, and given the fact beta version has no support from Microsoft, for this reason I'm here to complain about this disinformation between Intune and Graph, at least in beta version. There's no such option (usersloggedon) in v1.0.
