Since your MS Outlook account password is the same as your Microsoft account password, so resetting the latter will automatically set a new password for your Outlook account. To recover Outlook password, go to Outlook.com, click the sign-in button available on the top-right corner. Now, enter your Outlook email address and click the Continue button. As you don't remember the password, click the "Forgot Password?" link.
Enter an alternate email address and then type the captcha code. If you do not have any other email address and then click "Create a new one with Outlook.com". You will see a registration form, where you have to provide the required credentials to complete the signup process.
Once the process finishes, use this ID at the password reset page, and proceed to the Outlook password reset process. As you click the Next button, you will receive a password reset code on the provided email address. Get the code and use it to reset your Outlook password.
