For customers who sync Salesforce with Exchange, admins can customize how some standard Salesforce fields map to some standard Exchange fields. Admins customize field mappings from sync configurations in Setup. Sometimes admins can’t customize field mappings. - Admins can’t map custom Salesforce fields. - Admins can’t customize mappings for all standard Salesforce fields. For example, admins can’t customize mappings for fields that Lightning Sync relies on for matching during the sync process. The table indicates which mappings can’t be customized. ## Default Event Field Mappings for Microsoft Exchange
