Duplicate file across the tenant

Details

Summary

This report utilizes the new added Microsoft 365 scanning features of version 4.0.  The 4.0 tenant scan prompts the new Agent365 to collect a hash of the file content and store the hash in the database where it can be use to compare against other files that match in content.

This query is designed to show show the different joins work together to get the desired data.
