Hi there, mtnoel66,

I'm here to help ensure you're able to email invoices in QuickBooks Desktop (QBDT).

You'll want to secure the connection between QBDT and your email account. This creates an easier and safer connection to your email.

You should have Web Mail, Outlook, and QuickBooks E-mail 2020 option. Those methods are also available to other versions of QuickBooks.

if QuickBooks E-mail is grayed out, you need to validate your subscription. This is to ensure you're able to send email from QuickBooks. Just click the Check for valid subscriptions button, then enter your Intuit Account. See the attached screenshot below for your visual guide.

If that's not the case, you'll want to choose Outlook or Web Mail. Check out the Connect your email to QuickBooks Desktop for instructions and detailed steps.

I've added this link: What’s new in QuickBooks Desktop 2020 to learn the latest features and improvements in the system.

Let me know how this goes by leaving a comment below. Just mention my name and I'll get back to you with more troubleshooting steps.

Thank you and stay safe!
