Hello again, @Philip Coetzee. Thanks for keeping us updated.

I have additional troubleshooting steps that you can try to fix issues when unable to email statements in QuickBooks Desktop (QBDT).

To start, let's make sure to update your QuickBooks Desktop to the latest release. After that, download the QuickBooks Tool Hub and run the Print & PDF Repair Tool. It resolves common errors when you email forms through the software.  

To do this, here's how:

1. Download the QuickBooks Print and PDF Repair Tool.
2. Save the file, then open it (QuickBooksToolHub.exe).
3. Follow the on-screen steps to install and agree to the terms and conditions.
4. Once done, double-click the icon to open the tool hub.
5. Go to the Program Problems bar. 
6. Click on the QuickBooks Print & PDF Repair Tool button in green.

Once done, attempt to print, email, or save as a PDF from QuickBooks Desktop again.

If the issue persists, you can continue following Solution 2 on this article: Troubleshoot PDF and Print problems with QuickBooks Desktop.

I'm here anytime you have other concerns. Keep safe always, @Philip Coetzee.
