The usage reports available in the Microsoft 365 admin center, Teams admin center, and other places now include anonymized user information by default. The new default became active on September 1, 2021 and the organization setting applies to any usage data generated by the Microsoft Graph usage reports API, which means that some scripts might create reports less interesting and useful than before. It’s a good change for privacy, but will organizations persist with the new default?
