Managing personal Outlook.com account settings, security, and privacy
Hi Hadia78! This is Raech, an Independent Advisor and an Outlook.com user like you. I'm happy to help!
Indeed, that email is a phishing scam and not legitimate. Microsoft will never send emails to notify about closing email accounts. Accounts can only be closed manually by the owner, or if the account becomes inactive.
Please mark them as Spam or Phishing through the Junk button, never click on any links and delete those emails right away. More details can be found below.

I hope this helps clear the confusion. I'll be around in case you need any further assistance.
Sincerely,
Raech
