Setting Up Organization Emails and Getting Confirmation Emails so they work

Setting Up Organization Emails and Getting Confirmation Emails so they work

I'm having some difficulty setting up organizational emails. (See screenshot below). When I setup organization emails, and click to confirm, where do the confirmation emails go? I feel like I'm missing a step. What are the step-by-step instructions to setup organization emails? Do they need to exist as individual accounts?  How does this work?
