    Yes, it is possible to replace EWS with Microsoft Graph in the context of Service Center Service Manager (SCSM). Microsoft has announced the deprecation of Exchange Web Services (EWS) in Exchange Online, and it is recommended to migrate to Microsoft Graph for accessing mailbox and calendar data.

    To change from EWS to Microsoft Graph in your production environment, you will need to follow these general steps:

    1. Assess Current Usage: Identify all the existing functionalities in SCSM that rely on EWS for sending and receiving emails and notifications.
    2. Review Microsoft Graph Capabilities: Familiarize yourself with Microsoft Graph and its API capabilities that correspond to the functionalities you currently use in EWS. Microsoft Graph offers improvements in security, simplicity, and efficiency compared to EWS.
    3. Update Application Code: Modify the SCSM application code to use Microsoft Graph APIs instead of EWS. This may involve changing the authentication method to OAuth and updating API calls to align with Microsoft Graph's REST-based architecture.
    4. Testing: Thoroughly test the updated application in a development or staging environment to ensure that all functionalities work as expected with Microsoft Graph.
    5. Deployment: Once testing is complete and you are satisfied with the results, deploy the changes to your production environment.
    6. Monitor and Support: After deployment, monitor the application for any issues and provide support as necessary to address any problems that may arise.

    It's important to consult the official Microsoft documentation for detailed guidance on migrating from EWS to Microsoft Graph, as well as to ensure that you are following best practices for your specific version of SCSM.
