Hotmail account blocked

Hello,

My hotmail account is blocked. I was able to change my password manually as i remember my security question. however, even though i have changed my password after i login is still blocked requiring me to send a verification code which i do not know. How do i also send a verification code to an alternative email address which i have access on it?

How should i solve this problem immediately as all my client's contact are in there and i need to work with the email account!

Your kind attention is highly appreciated.
