Recently I have been setting up a few automations to ensure proper synchronization of different fields from Sales Cloud to attribute fields in Marketing Cloud.
I also wanted to set up an automation to synch Email Opt Outs.
According to the documentation:
Enabling the Email Opt Out field only in Sales or Service Cloud does not synchronize the subscriber status in the Marketing Cloud. Always click Marketing Cloud Unsubscribe on the record (https://help.salesforce.com/articleView?id=mc_co_unsubscribes.htm&type=5)
While I was testing, I found that the status of a subscriber was synching instantly and correctly when the Email Opt Out field was checked, even though I haven't set up any automation for this yet. In Sales Cloud we are using the HasOptedOutOfEmail field and it gets correctly reflected in All Subscribers list.
Has there been an update recently, or am I missing a piece of puzzle here?
