ews deprecation

About this tag
The ews deprecation tag covers Microsoft's phased retirement of Exchange Web Services (EWS) in Exchange Online, with key enforcement dates including a March 2026 block for frontline/kiosk licenses and a global cutoff in October 2026. Discussions focus on inventorying EWS dependencies in Azure AD app registrations, migrating workloads to Microsoft Graph, and using new tools like EWS usage reports and the Graph User Configuration API preview. Topics also include the dedicated Exchange hybrid app requirement and a September 2025 enforcement window for hybrid customers. IT administrators and developers will find guidance on planning migrations, avoiding service disruptions, and leveraging supported alternatives before EWS is fully deprecated.
