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. First, make sure that you meet either the [Einstein Activity Capture system requirements](https://help.salesforce.com/articleView?id=aac_system_requirements.htm&language=en_US) or [Lightning Sync system requirements](https://help.salesforce.com/articleView?id=exchange_sync_sys_req.htm&language=en_US). Then, complete setup for your chosen product. - If you choose Einstein Activity Capture, set up events to sync in one of these directions: Salesforce to Exchange, Salesforce to Google, or Both Directions. Review [Set Up Einstein Activity Capture](https://help.salesforce.com/articleView?id=aac_configure.htm&language=en_US). - If you choose Lightning Sync, set up events to sync in one of these directions: Salesforce to Exchange, Salesforce to Google, or Both Ways. Review [See the Big Picture for Setting Up Lightning Sync for Microsoft® Exchange](https://help.salesforce.com/articleView?id=exchange_sync_admin_implement_ex_sync.htm&language=en_US) or [See the Big Picture for Setting Up Lightning Sync for Google](https://help.salesforce.com/articleView?id=lightning_sync_admin_google_implement.htm&language=en_US). ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-sales-sales_productivity-264-0-0-production-enus/b2f6c36a-fa61-4a3c-9752-032ce1818a69/images/icon_note.png) Note Event capture and the sync directions Exchange to Salesforce and Google to Salesforce don’t generate event invitations for events created in Lightning Experience or the Salesforce app. Now when syncing event organizers add attendees to events, an invitation is sent from organizers’ Microsoft or Google accounts. Attendees with Microsoft or Google calendars can accept or decline invitations from those applications. Einstein Activity Capture or Lightning Sync then syncs attendee responses to Salesforce so that other reps with access to the event can see attendance statuses. #### See Also - [Considerations for Using Events in Lightning Experience](https://help.salesforce.com/s/articleView?id=sales.creating_events_lex.htm&release=264.0.0&type=5 "Keep in mind these considerations for creating, updating, and owning events in Lightning Experience.") - [Einstein Activity Capture](https://help.salesforce.com/s/articleView?id=sales.einstein_sales_aac.htm&release=264.0.0&type=5 "Eliminate manual data entry and transform a list of engagements into action.
