Migration from Exchange Web Services to Microsoft Graph
2 min
Steps to Enable Microsoft Graph for Delegation Features:
To migrate delegated mailbox and calendar functionality from Exchange Web Services EWS to Microsoft Graph, complete the following steps:
- Upgrade Email+ to version 5.5.0 or later.
- Update the Email+ App Configuration to enable Microsoft Graph support.
Note: Do not remove any existing EWS-related configuration keys during the transition.
- Enable the Graph API feature by adding the following value to the Key Value Pair enabled_features configuration:
- graph_api
Before enabling the graph_api feature flag and configuring the Microsoft Graph KVPs, ensure that Email+ version 5.5.0 or later is installed on user devices. Enabling this feature on earlier versions is not supported.
- Configure the Microsoft Graph settings:
- email_graph_host=graph.microsoft.com
- msal_graph_resource_scope=https://graph.microsoft.com/.default
- msg_min_allowed_auth_mode=modern_auth
- realtime_notifications_protocol=1
- Deploy the updated configuration to managed devices through your UEM/MDM console.
- Verify delegated mailbox and calendar functionality after deployment to ensure Microsoft Graph connectivity is working as expected.
Email+ will use Microsoft Graph API for delegated mailbox, shared mailbox, delegated calendar, and shared mailbox calendar functionality.
