Hi there, TheUser734. The verify rebuild tool should fix the issue.

Since it doesn't work, let's ensure that QuickBooks Desktop is updated to the latest release. QuickBooks provides periodic maintenance releases and software updates to address emailing issues, add new features or enhancements, and update compliance data. 

Here's how: 

1. Go to Help and select Update QuickBooks Desktop.
2. Click Update Now, then select Get Updates.
3. When the update finishes, close and reopen QuickBooks. 
4. Choose Yes when asked to install the update, 
5. When the installation finishes, follow the on-screen instructions.

If the problem continues, we can perform other steps via the Send forms. 

1. Sign in to QuickBooks Desktop.
2. Go to each invoice.
3. Uncheck Send Email and click Save.
4. Recheck the Send Email and save it again to repair the link.
5. Then send the forms.

In addition, I have included an article that will provide you with the deposit times for customer payments to your bank: Find out when QuickBooks Payments deposits customer payments.

If you still have queries or concerns regarding managing customer payments, feel free to respond anytime. I will continue to assist you. Take care!
