Error while syncing the leads with SFDC campaign

[Anonymous]

Hi,

I have a set of form registrants which I am trying to Sync with a particular SFDC campaign, but below is the error I am getting.

Skipped Skipped execution due to that the lead 12636345 is not a sfdc lead/contact

Can anyone help me understand. Thanks for your help!

Regards,

Well... are they in SFDC? Did you previously run a Sync Lead to SFDC ​step?
