Three-four years ago I set up a business domain name with Microsoft. Apparently I did not renew my domain name (greenebss.com) and do not have full functionality with my Outlook address. I have been able to sign in and send emails, but when I try to send to that account from gmail and other domains, the emails bounce back with the "DNS Error: Domain name not found" message. What steps can I take to restore my account? Thanks in advance for any help provided.
