Hi there, ga

I appreciate all your efforts in trying to fix the issue and sharing with us the result. Let me guide you in the right direction to get back on track.

Since you're still having an error after trying those troubleshooting steps, I suggest reaching out to our Customer Support team. They have tools such as screen-sharing (remote access) that can check your account why you're unable to send emails in QuickBooks Desktop.

Here's how to reach them:

1. Open QuickBooks.
2. Go to Help, then select QuickBooks Desktop Help.
3. Select Contact Us.
4. Give a brief description of your issue, then select Let's talk, and then choose a way to connect. Phone support may be limited due to volume.

You can check out these recommended articles for more details:

• Set up an email service.
• Error: Could not connect to the email server.
• Update to the latest release of QuickBooks Desktop.

That's it. Let me know how it goes or if you have any additional questions in sending emails. I'll be happy to help you out.
