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.
After your administrator initiates contacts sync for you, Lightning Sync creates a folder in your email application called Salesforce_Sync. You can find the Salesforce_Sync folder under your contacts directory. Any contacts that have synced from Salesforce to your email application are in Salesforce_Sync. Don’t rename, move, or delete the Salesforce_Sync folder, or syncing between Salesforce and your email application stops.
-
Ask your administrator which direction you’re set up to sync.
- If you’re set up to sync from Salesforce to your email application only, syncing is already in progress, and you don’t have to do anything else. Soon you can access your Salesforce contacts directly from your email application.
- If you’re set up to sync from your email to Salesforce or to sync both ways, it’s time to move the contacts that you want to sync into the Salesforce_Sync folder.
-
In your email application, select the contacts you want to sync. You can select multiple
contacts at a time.

- Move—do not copy—your selected contacts to the folder Salesforce_Sync. If you copy your contacts, you get duplicates, which are a hassle!
The contacts you move to the Salesforce_Sync folder begin to sync every few minutes. If you move numerous contacts to Salesforce_Sync, your first sync can take some time.
