Sending, receiving, and organizing email in Outlook.com
Hello, good day and thanks for your question. I understand that you have received a suspicious email that is related to your Microsoft account.
Microsoft does not send email to users with regards to this and this is clearly a scam or a phishing attempt to gain access to your account and it is best not to interact with this and it will be best to report it on this link https://www.microsoft.com/en-us/concern/scam.
