If you have access to the OneDrive account then you should be able to do so by replacing the assignment of the user account principal name to the $Account variable. Right now, it’s coded as follows:

$Account = (Get-MgContext).Account

This gets the account of the currently signed in user. Assign whatever account you want to report on to $Account and everything should work. The important thing is that the script uses delegated permissions, so if you don’t have access to the account, you can’t report its contents. To get past that restriction, you’d need to use application permissions and authenticate using an Entra ID registered app that has consent to use the required permissions.

There’s a GitHub link to the script at the bottom of the article… hopefully it’s visible!

I can’t seem to locate the script for “Report for a OneDrive for Business Account” here. While following the article, I did find the script for “Practical Graph: Report SharePoint Online Files in a Document Library,” but nothing for OneDrive. Could you please let me know if I’m missing something?
