Customer email addresses disappear when selecting "Combine forms to a recipient in one email" in send forms.

Thank you for providing detailed information and a screenshot, @ailoilo.

Since this behavior in QuickBooks is unusual and hasn't happened before, you can use the Verify tool to check your company file for errors or data corruption. Here’s how to do it:

1. Navigate to Window and select Close All.
2. Go to File, then choose Utilities.
3. Click on Verify Data.

If you receive a prompt indicating that data damage has been found in your file, proceed to rebuild your data to fix any identified errors or damage.

If QuickBooks detects no problems with your data, the issue may be related to the software. In that case, consider using the QuickBooks Tool Hub, which will quickly repair your program. To do this, you can follow the steps outlined in this article: Fix common problems and errors with the QuickBooks Desktop Tool Hub.

Let us know if you have any additional questions.

No problems detected with our data and I cannot use QuickBooks Tool Hub,  it is not allowed by Rightworks.

2. Choose Contact Us and enter a brief description of your issue. Then, Continue.

I am also having this issue, must be an error in a recent update, I've ran the tool hub several times recently, as I'm also having issues with the program crashing anytime i run payroll.  It hasn't solved any of my issues.

Also,  ever since the combine forms option was added, about every 3rd send, it errors out and crashes the program, the only  way to sent the emails is to switch if from outlook, to web mail in the preferences.
