Lenoxsoft needs to sync their Salesforce custom objects to Marketing Cloud Account Engagement prospects in order to run an automation rule. What is…

The fundamental requirement for syncing a Salesforce custom object with Marketing Cloud Account Engagement is establishing a link to a record that Account Engagement already recognizes and syncs. Account Engagement prospects are created from Salesforce Leads and Contacts. Therefore, the custom object in Salesforce must first be related to a Lead, Contact, or Account record via a lookup or master-detail relationship. This relationship is the conduit that allows Account Engagement to associate the custom object's data with the correct prospect, making it the foundational first step in the entire configuration process.

A. The Account Engagement custom object is created after the Salesforce object is properly configured with the necessary relationship, not before.

C. Adjusting sync behavior is a configuration step performed after the custom object is created and mapped in Account Engagement, not as the initial step.

D. The Salesforce custom object must be created and configured before it can be included in any sync; a full database sync is not a prerequisite.

1. Salesforce Help, "Considerations for Using Custom Objects": This document explicitly states the primary prerequisite. In the "Guidelines" section, it says, "To use a custom object with Account Engagement, it must have a relationship with a contact, lead, or account record in Salesforce." This confirms that establishing this relationship is the initial requirement.

2. Salesforce Help, "Create a Custom Object in Account Engagement": This guide outlines the procedural steps. The process begins with the assumption that the Salesforce custom object is already created and related to a standard object. The first step listed for the Account Engagement administrator is to navigate to Account Engagement Settings > Object and Field Configuration > Custom Objects, which can only be done after the prerequisite in Salesforce is met.
