Managing personal Outlook.com account settings, security, and privacy
Hi
This looks like a phishing email. Threatening to cut off account access unless you download an “update” is a common scam tactic.
Don’t click Download or open any attachments. In Outlook, select the email and choose Report > Report phishing.
