Managing personal Outlook.com account settings, security, and privacy
Greetings, Nick! My name is Arif, and I will assist you today.
It looks like a spam email. It is better to disregard the email and try to block the sender's email and domain "if it is not a Microsoft domain", as well as the IP address.
Once you have taken all the above steps to increase your security, make sure to reset your account password and set up a stronger one. If you are using a Gmail account, you can make your account more secure by using Google Authenticator or Microsoft Authenticator. You can download these from your Google Play or App Store and then set them up on your account.
Warm Regards,
Arif
