Microsoft has announced that IT administrators now have the option to reactivate the Exchange Web Services (EWS) API in Exchange Online.

With the announcement to reactivate the API, Microsoft is responding to numerous feedback from users and businesses that rely on the functionality of EWS apps. To reactivate the EWS API, IT administrators must follow specific instructions provided by Microsoft.

These instructions include steps to configure the Exchange Online settings to make the API accessible for the affected applications. The decision to reactivate the EWS API comes at a time when many companies are transitioning to cloud-based solutions. Microsoft has emphasized that support for EWS apps remains crucial to ensure the integration of third-party applications. The reactivation of the API could also impact the development of new applications that access EWS. Developers may be encouraged to adapt their applications or integrate new features that utilize the restored API.
