We had an issue a few days back where our Salesforce password we use for syncing in Marketo expired, so we had to change it. For a brief time Marketo could not sync to Salesforce.
Is there a way to display which leads were not synced to Salesforce? or just leads we have in Marketo that are not in Salesforce?
Now that Marketo has access to Salesforce again, shouldn't those leads be synced? Marketo says it's syncing but we do not see those leads in Salesforce.
If leads are not sync'ed at all with SFDC, just run a smart list with the filter SFDC Type [person] is empty. This will give you all the leads that are in Marketo and not in SFDC.
Please also note that Marketo leads are not automatically pushed to SFDC. There are only sync'ed when you run some SFDC related flow steps.
