Having trouble with QuickBooks not sending emails? You’re not alone. This common issue can happen due to incorrect email settings, problems with your email provider (like Outlook or Gmail), or damaged QuickBooks components. If you're receiving error messages like “QuickBooks is unable to send your emails” or nothing happens when you try to email an invoice, there are a few things you can try.

First, check if your email preferences are set up correctly under Edit > Preferences > Send Forms. Make sure the right email client is selected. If you're using Outlook, ensure it's set as the default mail app in Windows. Also, update QuickBooks and your email client to the latest versions.

Still not working? Try running QuickBooks as an administrator or repairing the installation.
