We have moved to a new D365 instance and had to move to a new Marketo instance which has been set up. I have a a lead in Marketo and we manually Sync to Microsoft as a Lead. In D365 - we complete some additional details and then progress the lead to an opportunity. In D365, this creates the opportunity and converts the lead to a contact.   In our old instance - the lead in Marketo would get updated to a contact. Currently, with new instance, the lead is kept in Marketo, and a Contact is created - so we have duplicates in Marketo. A Lead with some of the info and a Contact with some info and the opportunity info completed.   Does anyone know where the problem would be? Would this be in D365?   Thanks Sam  ... View more
