Hi there, @Kimba22.

At this time, the issue of sending emails through QuickBooks is still on-going. Rest assured that our product engineers diligently working for a fix.

As a workaround, you can follow the troubleshooting steps shared by my colleague JonpriL to fix the password issue.

To ensure you'll get an update about the resolution status, I recommend reaching out to our Customer Support Team again. They have to collect personal data to add your company to the list of affected users and provide this investigation number for easy tracking: INV-38793.

To reach them, go to the Help menu, then select QuickBooks Desktop Help to talk with a live agent.

If you have any other questions, feel free to comment below. Thank you for your patience while we're working on this.
