To permanently close your Outlook.com email account, you need to close your Microsoft account. When you close your Microsoft account, your email and contacts are deleted from our servers and can't be recovered. If you use your Microsoft account with Xbox, Skype, OneDrive, or other Microsoft services, you'll no longer be able to access those services.
If you want a fresh start, you can create a new account without closing your old account. This will give you a new Outlook.com email address, inbox and From address, and you won't lose access to your existing email and contacts.
If you want to use a new email address with your existing Outlook.com account, you can add an email address to your Outlook.com account. This will give you an additional email address which uses the same inbox, contact list, and account settings as your primary email address.
If you just need a new name to be associated with your account, you can change your profile photo or name.
If your account has been hacked and you want to recover it, see My Outlook.com account has been hacked.
