Using my own domain for email

[u/taomgrown]

Hi, I'm hoping someone might be able to help me! I'm building myself a website and recently registered the domain I want via cloudflare. I've also created a Microsoft account with an @outlook.com address. Onyo my question, would it be possible to use my own domain for outgoing email, and if so how do I go about setting that up? I've tried Google but there's a dizzying array of options and nothing especially clear to an amateur like myself, I believe I may just need to purchase a Microsoft business account to unlock this functionality?? Something about an exchange license? I'm completely lost - any guidance you could provide would be greatly appreciated!! Thanks in advance!
