When a record in salesforce got archived, the visibility of this record will be removed from marketo. How can I handle this scenario? I want to identify in marketo those records that become archived in Salesforce
Since Marketo is unable to retrieve data from these records, you will need to create a workflow in sfdc to change a field and allow Marketo to read it before archiving the record. Once the data is retireved, you can safely archive the record and then use that field to manage them in Marketo.
