# Lightning Sync

Lighting Sync is retiring in 2027. Migrate to Einstein Activity Capture to continue syncing events and contacts from a connected account to Salesforce. If you use Lightning Sync with Microsoft® Exchange Web Services, upgrade your connection to Microsoft Graph before October 2026 to avoid service disruption.

- **[Upgrade Microsoft® Exchange Web Services to Microsoft® Graph in Lightning Sync Before October 2026](https://help.salesforce.com/s/articleView?id=release-notes.rn_sales_productivity_ls_ews_retirement.htm&release=264.0.0&type=5)**  
    Microsoft announced the retirement of Exchange Web Services (EWS) for Microsoft Office 365 starting October 2026. Lightning Sync configurations that use EWS won’t capture or sync data after this retirement. To avoid service disruption, upgrade to the Microsoft Graph authentication method in Lightning Sync setup now.

    Lightning Sync is scheduled to retire in 2027. Migrate to Einstein Activity Capture to continue syncing contacts and events between Microsoft® or Google applications and Salesforce. Use the Lightning Sync migration tool to complete the process.
