I already had Office 365 and just bought a domain name. How do I set up a domain email and link in Outlook? Do I have to purchase the email plan from godaddy?
Well you definitely have to purchase an email service, either from GoDaddy or MS. If you are NOT hosting a website with Godaddy and you just need email attached to a domain. I would go with MS Exchange On Line. It is basically your own email server. MS Exchange On Line also offers an option for using your domain name and "attach" it to the email server. Your going to have to read up on that portion. Go here for that info Exchange Online | Microsoft Docs
