We still support the ability to log in to Outlook.com with your existing custom domain email address, but admins can no longer manage accounts in the domain. These accounts are still able to send and receive email, and you don’t need to make any changes. To access an account, please log in via Outlook.com. Domain administrators who wish to continue managing email addresses in their domain should migrate to Office 365.
