The Top OneDrive Users report shows you the users who have the most number of items in their OneDrive for Business.
The Data Table
The data table lists each user, the number of items in their OneDrive for Business, and the last time modified a file. You can add, remove or re-order these columns to display additional information such as when their OneDrive for Business was created.
This report can be filtered, allowing you to generate bespoke reports about the OneDrive activity in a particular Department, Country or any other category you choose.
As with all of the reports, this information can be customized, filtered and scheduled.
