Export a list of Office 365 users and their licenses in all customer tenants with delegated administration

Here’s a script that reports on all licensed Office 365 users in all of your customer tenants, and exports their details and their license info to a CSV file.

It uses your Office 365 delegated admin credentials to retrieve all of your customers.

Then it pulls user and license info from each customer.

It appends this information to a CSV as it runs.
