Important

Starting in Winter ‘21, [Lightning Sync isn’t available](https://help.salesforce.com/apex/HTViewSolution?urlname=Lightning-Sync-End-of-Sale&language=en_US) 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](https://help.salesforce.com/s/articleView?id=sales.lightning_sync_move_parent.htm&type=5&language=en_US) to move to [Einstein Activity Capture](https://help.salesforce.com/articleView?id=einstein_sales_aac.htm&language=en_US) before Lightning Sync retires in 2027. Before you migrate, review [Compare Einstein Activity Capture and Lightning Sync](https://help.salesforce.com/s/articleView?id=sales.email_integration_admin_eac_vs_lightning_sync.htm&language=en_US) to understand what to expect when you migrate.

If your org is exempt from migration because of a licensing issue or if your org doesn’t support Einstein Activity Capture, you won’t see the migration tool in Lightning Sync.

## 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.

## Lightning Sync for Microsoft Exchange

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.
