Sending, receiving, and organizing email in Outlook.com
Hello,
If you are trying to make any security changes to your account, such as resetting your Password, you will have to verify your identity using the recovery Phone number, email address or the authenticator app you've set up in your account before.
If you only have the recovery email address and it is currently not active, you will have to replace it.
That is, on the Verify Your identity screen, select 'I don't have any of these' and follow the prompts to replace it.
Note - If you remove all of your previous security information and replace it with something new, your account will be put into a restricted state for 30 days.
