I have run the below query in MS Graph to get user activity.
https://graph.microsoft.com/v1.0/reports/getOffice365ActiveUserDetail(period='D180')
I got deleted users in the result. And also, there is a flag called Is Deleted in the response, but it is false for all records. I have deleted users two days before from this question posted. I am getting always false in Is Deleted flag. I have searched Ms docs to find the purpose of this flag. Unluckily, I am not able to find it. Please help me to find out this.
