How Your Events Sync with Lightning Sync

Learn how Lightning Sync handles your events when you’re set up to use Lightning Sync.

Important

Starting in Winter ’21, Lightning Sync isn’t available to new Salesforce customers. If you’re on Lightning Sync, use the Lightning Sync migration assistant for a seamless transition to Einstein Activity Capture, our long-term solution for syncing contacts and events between Microsoft® or Google applications and Salesforce.

In October 2026, Microsoft 365 replaces Exchange Web Service (EWS) with Microsoft Graph API. We recommend taking this opportunity to transition from Lightning Sync to Einstein Activity Capture with Graph API or another supported connection method. See Upgrade Microsoft Office 365 Authentication Method to Microsoft Graph in Einstein Activity Capture.

• Event Sync
  If you’re set up for Lightning Sync, learn how we match your Microsoft or Google events with relevant Salesforce events, leads, and contacts. You can also learn what we do when we can’t resolve a match, which events we sync, and how often.
• Events Automatically Related to Contacts or Leads
  Lightning Sync can automatically relate Microsoft or Google events to relevant contacts or leads in Salesforce. Learn how that feature works, and how it interacts with other Salesforce options.
• Event Series Sync
  If you use Lightning Sync, your Salesforce admin can set up your event series to sync between Microsoft calendars and Lightning Experience or the Salesforce mobile app. Admins set up event series sync from your sync configuration in Setup.
• Event Attendee Sync
  If you sync events with Lightning Sync, invited contacts, leads, and other Salesforce users sync to Microsoft® Exchange or Google calendars. Events sync for the organizer and attendees according to the sync direction that Salesforce admins have set for the organizer.
• Event Delete
  You can set up sales reps to delete events—from both their calendar and Salesforce—in one action.
• Private Event Sync
  When you select the Sync private events setting in your sales reps’ Lightning Sync configurations, events that reps mark as private can sync between Salesforce and your Microsoft or Google calendar. When a private event syncs, it’s marked as private in both calendar applications. However, some situations aren’t supported for private events, such as attendee sync and automatically relating contacts or leads, that.
• Event Field Sync
  When you use Lightning Sync to sync events, fields from your Salesforce events are mapped to the same or similar fields in your external calendar. Learn which fields sync and how fields are mapped between applications by default. Plus, see which Microsoft® Exchange field mappings Salesforce admins can customize.
• Sync for Events Restored from the Recycle Bin
  When you’re using Lightning Sync, learn which kinds of events restored from the Recycle Bin start syncing again.
