Issue
Leads are members of a Marketo Program that is synced with a SFDC campaign, but there are some leads that have not synced to SFDC.
Solution
1.) First check to see if this was caused by a Salesforce Sync Error. This can be checked in the Admin area under Admin > Salesforce > Sync Errors. Additionally, errors will appear under Notifications, check for the subject 'Salesforce Sync Error: Unable to Add Leads to Campaigns'. This will list the details of the SFDC Error and a list of sample leads along with the Salesforce campaign that they failed to sync to
Example error:
INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY: insufficient access rights on cross-reference id
Sample Leads: Salesforce Campaign
lead1@mail.com Campaign name
lead2@mail.com Campaign name
2.) This can also be caused by mismatched statuses between the Marketo Program and the SFDC Campaign. If the status doesn't exist on both sides, leads with the problem status can fail to sync.
3.) This can also be caused by a backlog for the program/campaign sync. Check with Marketo Support to see if a backlog is present.
