We're having intermittent issue emailing invoice with error message "We're sorry, but we can't send email right now because of a problem on our end." how to resolve?

Let's resend the invoices without special characters in the email address field, cindy28.

That is the reason why QuickBooks won't send them. Please remove those extra characters then click on the Save and send button.
