In the past my sales reps have been able to preview emails sent from the sales insight section of a leads record, simply by clicking on the subject line in the email tab.
All of a sudden they are no longer able to do so. When they click on an email subject line they are prompted to log into Marketo, and they don't have Marketo accounts, nor have they ever.
I think it might have something to do with our API hitting it's limit last week, which caused us to reset our Marketo user's password in Salesforce and also reset our sync token in Marketo.
Has anyone experienced this? How did you fix it? Thanks!!
