We are thrilled to announce the release of Exchange Web Services (EWS) Usage reports in the Microsoft 365 Admin Center—a feature designed to simplify and enhance administrative oversight for tenants in their effort to remove EWS dependencies. This marks another milestone in our commitment to providing actionable insights and tools for our administrators, ensuring they have everything they need to manage the retirement of EWS.

Why is this relevant to you?

Exchange Web Services (EWS) will be deprecated starting October 2026, a decision announced some time ago to encourage users’ transition to modern, secure solutions like Microsoft Graph. This retirement reflects Microsoft’s commitment to scalability, security, and compliance while phasing out outdated technologies.

To help administrators assess their dependence on EWS, the Microsoft 365 Admin Center now offers EWS Usage Reports. These reports provide key insights into usage trends, enabling proactive adjustments and smooth transitions ahead of deprecation. You can also download the data for further analysis and archival.

How to Access EWS Usage Reports

The reports are accessible to WW tenants via the Microsoft 365 Admin Center. To view them:

• Log into the Microsoft 365 Admin Center


• Navigate to the “Reports” section


• Select “Usage” and from the Overview page select Exchange > EWS Usage.

A dedicated guide with step-by-step instructions is available here: Microsoft 365 Reports in the admin center – EWS usage – Microsoft 365 admin | Microsoft Learn

Who can access those reports?

Microsoft 365 Admin Center reports are available exclusively to out Worldwide (WW) customers. If you need to understand EWS usage in government or other sovereign clouds, please refer to this project, which provides a self-service tool to retrieve usage data.
