Coming soon: A new Exchange Web Services (EWS) usage report in the Microsoft 365 admin center that provides insights into the non-Microsoft (third-party) applications in your tenant that use EWS. The report provides detailed information on the specific actions performed by these applications and their call volumes over a selected period. The new report enhances your ability to understand EWS activity prior to EWS deprecation in Microsoft Exchange Online.
