Email counts from office 365

[Anonymous]

Hi PowerBI'ers

We would like to bring back email counts, sent , received, read, for all users per day from Azure / Microsoft Graph / Outlook API / Office 365 ?

We would like to bring back meetings / events for all users per day from Azure / Microsoft Graph / Outlook API / Office 365 ?

For the last three months would be handier than just the last month.

I have used GET https://reports.office.com/pbi/v1.0/  but no avail since these are aggregated for the whole of last monthy always ands not split by day.

Also tested was GET https://graph.microsoft.com/v1.0/  , but I cannot retreive all users events as the API rejects making seperate calls for each user for this volume, and I not sure how to make $batch requests iwith the MS Graph API for the 264 users I want to query.

Also if anyone knows how to use this in Power Bi very useful . Many thanks :
