Thank you for providing the exact error message you received when attempting to send statements through QuickBooks Desktop (QBDT), Limary. This information helps identify potential solutions and ensure a smoother workflow moving forward.

First, ensure you've set up functional emails in the Send Forms Preferences. You can refer to the steps shared by my colleague Sherrie above. This way, you can smoothly transmit statements to your customers.

After doing so, if you're still unable to send statements or get the same prompt message, I suggest running the Verify/Rebuild tool. This will help detect system errors or damaged data and refresh the QuickBooks company file.

Before performing this process, please create a backup copy of your company file so that if changes occur, you can restore and undo it easily.

First, let's rebuild the data.

1. On the top menu, click File.
2. Pick Utilities.
3. Select Rebuild Data.
4. Click OK if you receive a prompt to back up your company file.
5. When you get the message that Rebuild has completed, hit OK. 

To ensure your file has no errors or data damage, we can verify your company data. 

1. Go to the Filemenu.
2. Click on Utilities.
3. Select Verify Data. 

The troubleshooting steps outlined above should help you overcome the prompt message you received. By following these measures diligently, we aim to resolve any issues swiftly and effectively.
