After setting up your business email as the default but your customer starts emailing using your personal one, you'll want to perform some troubleshooting steps. There might some issues with the data that can cause this behavior.
To start, let's ensure to update the QuickBooksDesktop so you have the latest version. Then, rebuild your file to fix data damage.
Here's how:
- Go to the File menu.
- Select Utilities and then choose Rebuild Data.
- On the QuickBooks Information window, select OK. Follow the onscreen steps to save a backup.
- Let the tool repair your file.
- When the tool finishes, select OK.
- Go to the File menu again and then select Utilities and choose Verify Data.
- Let the tool check your file for data issues.
