Allow me to chime in for a moment and help make sure that you can send invoices to your customers in QuickBooks Desktop (QBDT).
First of all, I appreciate you performing all the steps provided by my colleagues above. Since the issue still persists even after generating third-party app password in your Yahoo! Mail, I highly suggest contacting our Phone Support team so they can check it out using their screen-sharing (remote access) tool and fix it for you.
You can check out this article for the detailed steps on how to reach them: Contact the QuickBooks Desktop Customer Support Team.
After contacting them, I'm confident that you can go ahead and send invoices to your customers.
Please let me know how it goes or if I can be of additional assistance. I'm always here should you have any follow-up questions or concerns. Take care and have a great rest of the day!
