            Lightning Sync Security

            Lightning Sync is designed to sync contacts and events simply and securely between Salesforce and your Microsoft or Google email service. Learn about how that design impacts how data flow between systems and the configurations requirements you must meet to setup the product.

            Required Editions

            Available to sync records from: Salesforce Classic, Lightning Experience, and the Salesforce mobile app
            Available to set up from: Salesforce Classic and Lightning Experience
            Available in: Professional, Enterprise, Performance, Unlimited, and Developer Editions with Sales Cloud, Service Cloud, and Lightning Platform
            Important
            Important

            Starting in Winter ‘21, Lightning Sync isn’t available to new Salesforce customers. Use Einstein Activity Capture to sync events, contacts, and emails between your connected account and Salesforce.

            If you have Lightning Sync, use the migration tool to move to Einstein Activity Capture before Lightning Sync retires in April 2027.

            If you use Lightning Sync with Microsoft Office 365 and Exchange Web Service (EWS) as your authentication method, complete your migration by August 2026 to avoid service disruption. In October 2026, Microsoft retires EWS for Microsoft 365 and replaces it with Microsoft Graph API. After migrating to Einstein Activity Capture, upgrade to the Microsoft Graph authentication method. See Upgrade Microsoft Office 365 Authentication Method to Microsoft Graph in Einstein Activity Capture.

            This change affects all orgs except those using Government Cloud.

            • Lightning Sync Design and Data Flow
              Lightning Sync is designed to simplify the data flow between Salesforce and your email service.
            • Lightning Sync Connection Security
              Salesforce takes your data security seriously. Lightning Sync leverages standard Salesforce security measures when establishing a connection with your email service.
            • Security Measures Specific to Your Connection Method
              When you prepare your email service to connect with Salesforce, you create touchpoints in which the systems connect to sync data. Lightning Sync provides several methods for connecting systems. The security measures and other benefits that impact you depend on which connection method you select when you set up the product. See which connection methods are available to you based on the email service that you’re using. Then learn about the security measures that impact that connection method.
            • Lightning Sync Transactions
              Review the transactions made by Lightning Sync in response to the work your users complete in Salesforce, and the order in which they occur.
