Hate to be the bearer of bad news but once an alias address is deleted, the action is permanent and that address can never be recovered or reused by anyone at any time. I’m sorry, I know how this situation is frustrating for you and I wish could do more to
Acordding to Microsoft – If you remove an alias that’s an email address from a Microsoft domain (like @hotmail.com, @live.com, @outlook.com, or @msn.com), you’re permanently deleting the alias and it can’t be associated with any Microsoft account again.
-Aliases can’t be moved from one Microsoft account to another.
-If you remove your alias from the account it’s on today, it will be deleted from Microsoft systems and isn’t recoverable, so you’ll no longer be able to use it to send or receive emails.
-Microsoft doesn’t recycle aliases once they are deleted. This means it won’t be available again as an alias or new account to you or anyone else at a later time.
