Hello,

If Outlook.com shows “this email is part of reserved domain,” Microsoft has permanently blocked the alias and you cannot add it again. Once you remove an alias, recovery is not guaranteed, and some addresses become unavailable for security reasons. Support agents cannot manually restore reserved addresses.

Did you delete the alias from a Microsoft account or close the entire account? If the system shows reserved domain, there is no supported way to recover it. Your only option is to use a new alias and update your email on important accounts.
