We need to be able to distinguish between shared mailbox and normal user via Microsoft Graph!

At this point, the user that is being retrieved by Microsoft Graph doesn't have any properties that would make it clear that this user is a room or a shared mailbox. But for our product we need this information!

Could you please ask this question on Microsoft Q&A as it is not to do with Search but broader Microsoft Graph. There are teams there that monitor those forums https://docs.microsoft.com/en-us/answers/topics/microsoft-graph-users.html

@Jeremy Thake I've already asked the same question on Q&A but haven't got any answers that would explain to me when we should expect this functionality.

Use PowerShell instead of MS GRAPH.

Why?
But anyway you cannot do what you want using MS GRAPH.
