“Microsoft account unusual sign-in activity”, as the message suggests, is an alert message issued by Microsoft account security when it detects any unusual sign-in attempts into your account. This message usually appears when a device that your account does not recognize is making the login request.
Apart from someone trying to access your account, the message can be because of a device that not yet registered. The message can also appear if the account is being accessed from a location 300 miles or further from previously logged in location, with a new IP address.
To fix this, users can disable the warning message by changing alert settings from their Microsoft account. However, if the threat is legitimate, it is best for you to update your account’s security to avoid any theft, leak or loss of information.
