I recently added a domain to my domains.live.com account, simplyhealth-calm.com , that I admin and was setting up email for. When adding a user I got an alert that the user already existed and it gave me the option to import that account over (*** Email address is removed for privacy ***)

This person does not know her password as the account is old and inbox is set as inactive. I tried the forgot password options on outlook.com and it says the account doesn't even exist. How can I reset the password, make the mailbox active, etc ?
