Microsoft OneDrive Powershell Script

We need a powershell script written to compare file counts against OneDrive for Business with file counts in a separate OneDrive for Business, (for around 100 users total). For example, here is the high level code we need: $csv = import-csv [login to view URL] Where [login to view URL] contains: Source,destination user@[login to view URL] , user@[login to view URL] (This file will contain about 100 user accounts) For each user: $sourceCount = crawl through onedrive for source user to get total item count $destinationCount = crawl through onedrive for destination user to get total item count Report Output should contain the source and destination user along with the file/s that are missing in the destination environment. Select sourceuser, sourcecount,destinationuser,missing file path | export-csv [login to view URL] Note: I wrote some code that helps connect to the tenant and perform a crawl, but this code lacks the ability to retrieve file level information to perform comparison. [login to view URL] I think the DriveItems REST API may be able to finish the job. [login to view URL] The need is for a report comparing the source and the destination to let us know if all files were copied from the source OneDrive tenant into the destination OneDrive tenant.
