You don't need any special account in Office 365/Azure in order to run the script (actually, just run it with your normal/local account!). What you need to do is go to the Azure management portal (portal.azure.com), then go to "App registrations", and click on "New registration". From there, give it a name, create a secret, and in "API permissions" give it the permissions I mention in the script for "Microsoft Graph".
Then, you use the details from the app registration to update the $ClientID, $ClientSecret, and $TenantID properties in the script. This is what the script uses to authenticate against Graph API and retrieve all the information from meeting rooms.
