Lightning Sync
Starting in Winter ’21, Lightning Sync isn’t available to new Salesforce customers. If you’re on Lightning Sync, use the Lightning Sync migration assistant for a seamless transition to Einstein Activity Capture, our long-term solution for syncing contacts and events between Microsoft® or Google applications and Salesforce. In October 2026, Microsoft 365 replaces Exchange Web Service (EWS) with Microsoft Graph API. We recommend taking this opportunity to transition from Lightning Sync to Einstein Activity Capture with Graph API or another supported connection method.
