We enabled sync out Marketo to Salesforce once, but because of some errors we stopped it by changing security tokens.
We currently have Salesforce Contacts on our Marketo.
we don't want Marketo to update Salesforce contact data.
Also we would like to delete them only on Marketo because we no longer need those Contacts in our Marketo.
We tried to delete it by "Delete Lead" commando on Lead Database.
The contact still exists although the dialog said "Succeed".
We searched and reviewed the following related article but ours didn't run like on this.
