Lightning Sync System Requirements
Confirm that your Microsoft® Exchange-based server or Google Workspace account meet these system requirements before you set up your sales reps for Lightning Sync.
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 |
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 for Google
The service account connection method is available for companies working from Google Workspace. Einstein Activity Capture supports the Basic, Business, and Enterprise editions of Google Workspace.

The service account and OAuth 2.0 connection method are available for companies working from Microsoft Exchange.
Lightning Sync doesn’t support hybrid Exchange server deployments that include both Exchange Online and on-premises Exchange servers. Syncing to even one of the servers in a hybrid deployment isn’t supported.
