I can no longer e-mail from within the program.

I can imagine the situation you’re in right now, @leeortiz.

Please know this isn’t what I want you to experience with QuickBooks. Let me make it up to you by ensuring you’ll be able to email your invoice in QuickBooks Desktop (QBDT). 

I recommend downloading and running our QuickBooks Tool Hub. This tool scans your program for unusual errors and fixes them right away. To begin with, you can follow the steps below.

1. Close QuickBooks.
2. Download the recent version (1.4.0.0) of the QuickBooks Tool Hub. 
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
6. Select Program Problems.
7. Then click Quick Fix my Program first.

For more details about the process, check out this article for reference: Fix common problems and errors with the QuickBooks Desktop Tool Hub,

If the issue persists, after performing the steps above, I recommend contacting our Support team. I understand you’ve already contacted them. However, it would be best to reach out to them again as they can look into your account and create an investigation ticket if necessary.

For the meantime, you’ll want to save your invoice as a PDF file and attach it to your email. Open the invoice you want to send, click the Save drop-down and select Save As PDF. 

Furthermore, I’ve added this link that you can utilize in case you need to learn how to customize email templates in the future: Create custom email templates in QuickBooks Desktop.

Let me know if you need further assistance in sending email invoices in QBDT. I’ll be around ready to help and work with you again. Stay safe and keep well.
