I’ve have just uploaded a new script to my public Office 365 repo. Here is the direct link:
https://github.com/directorcia/Office365/blob/master/graph-odfb-get.ps1
The script will use the Microsoft Graph to create a summary report of users ODFB, which can also be output to a CSV file.
You will need to have the Graph PowerShell module installed. When you run the script you will typically need to consent to the above permissions. These can be found in the Users area of the Graph documentation.
The first thing the script will do is connect to the Microsoft Graph and you will generally be prompted to login with a user who has suitable permissions. Once that is complete a list of users will be displayed as shown above.
The script will then look at each user found and determine whether they have a ODFB assigned and enabled as shown above. Not all users in your tenant may have a ODFB.
For users that do have a ODFB the stats on these will display including total size, used and deleted as shown above.
If you use the –csv switch on the command line when you run the script a summary CSV file will also be generated in the parent directory.
Hopefully this helps get a quick summary of all your users ODFB usage.
