We use the MC Connect to sync our SFDC Contacts in SFMC.
We cannot use the standard fields like "IsDeleted" for filtering because we have specific requirements which Contacts to sync. Thats why we created a custom boolean field.
Imagine 1) one Contact matches the filter criteria (MCSync__c = true) and is snyced by MC Connect and part of the Synchronized DE in SFMC. Imagine 2) Contact is deleted physically in SFDC.
What does the MC Connect in that case? Will the Contact remain in the Synchronized DE? Is the Contact deleted in the Synchronized DE?
(We do not have access to IsDeleted in our custom field MCSync__c)
