Hi there, @SNun.
I'll share with you some basic troubleshooting that can fix the error. This way, you can send the edited invoice email to your customers.
First, let's make sure to use the latest version of the following before sending the invoice:
- Version of Outlook
- Version of Windows
- Any Microsoft updates installed in the previous week or so
You can also update QuickBooks Desktop to its latest release to fix the issue. Doing this can help resolve some minor data problems in your company file.
- Go to the Help menu and select Update QuickBooks Desktop.
- Click the Update Now tab and select Get Updates to start the download.
- When the download finishes, restart QuickBooks.
- When prompted, accept the option to install the new release.
Once done, try sending the invoice again. If you're still getting the same result, run the Verify and Rebuild Data tools. These will help us identify the most commonly known data issues within a company file and fix it.
Additionally, you can run several reports to tell where your company stands. These offer critical information about your business and finances.
The Community always has your back, so please let me know if you have any other questions. I'll be more than happy to help. Keep safe.
