Microsoft EWS Access Change – Action Required Soon

This informational notice about Microsoft’s upcoming EWS access changes is now closed. No further updates are expected. Please ensure your organization has made the necessary adjustments to avoid service disruption

Microsoft has announced a change to Exchange Web Services (EWS) access in Exchange Online, effective at some point in April 2025 (Microsoft has not provided a specific date for this change). Once this change has been made, EWS access will only be allowed if both the organization-level and user-level EWSEnabled flags are set to True.

To avoid any service disruptions, please ensure that EWS is enabled at both levels in your Microsoft 365 tenant. If either flag is set to False, EWS requests will be denied, and your migrations or services relying on EWS may fail.

We strongly recommend reviewing your settings in advance.
