Welcome to the Community. QuickBooks Desktop is a flexible program that simplifies the way you manage your books. I'd be glad to help.
Based on what you've described, I feel you'd benefit more from contacting our support team outside of the community. They'll be able to point you in the right direction regarding sending invoice emails through Outlook. You can review this article to reach out to our support team.
