Exchange online devices not enrolled

[Skipster311-1]

Hello 

Is there a way to identify non intune enrolled devices that are accessing exchange online ? Im looking at the below KB article but not sure if this command will help me ?

@Skipster311-1 Have you been able to get devices not listed in Intune but fetching mails from Exchange?

Got exactly the same task now and don't know how to approach it and collect all devices that I cannot see in Endpoint Manager.
