Hi @SoftwareTeacher,
Being able to email invoices is imperative to a business. Are you using Outlook as your email provider? If so, we have an open case about QuickBooks is unable to send emails to Outlook. As a workaround, you'll want to use Webmail.
Let me guide you how:
- Go to Edit, then Preferences.
- Choose Send Forms, then select the Web Mail radio-button.
- Click Add, then enter another email provider.
- Hit OK.
If you're not using Outlook, you can run the QuickBooks File Doctor. This tool fixes company file issues. Please see this article for the detailed steps: Fix company file and network issues with QuickBooks File Doctor.
I'm also attaching this handy article about the unrecoverable error in QuickBooks Desktop for more recommended solutions.
