Thank you for posting your concern here in the Community, @valley elect.
Let's get this sorted out by checking the web mail's settings in the preferences. One of the possible reasons why you're unable to send an invoice via email is that the email preferences were being set incorrectly.
Before we start, may I know what email provider you're using to send your invoices in QuickBooks? Any additional information would help us provide the best resolution to your concern.
Here's how to check your webmail's preferences:
- Go to the Edit menu, then select Preferences.
- Click Send Forms from the left menu.
- In the My Preferences tab, select the email account you're using. Then, click Edit.
- Mark the SSL box, or just select Default.
- In the Server Name field, make sure the server name matches your email provider's settings.
I'm adding this article for more details: Fix Error: Could not connect to the email server.
