Greetings, @ACES050614. 

It's great to see a new face here in the Community. Let me point you in the right direction to get this resolved. 

I suggest contacting our Customer Support Team so you can utilize their screen share tool. They'll be able to walk you through some additional steps to fix this problem. Here's how: 

1. Go to the Help menu. 
2. Choose the QuickBooks Desktop Help option. 
3. Click the Contact Us hyperlink. 
4. Give a brief description of the issue and hit Let's talk. 
5. Scroll down and hit Let's talk. 

It's that easy! 

Keep me updated on this problem. I want to ensure that you're able to get back to running your business. Have a splendid day! 

I was on chat for 2.5 hours and still cannot send several invoices in one email.  Very frustrating!
