Hi I received an email from the ''hotmail team'' requiring that I provide private information in order to confirm my account because of some hackings that have occured? I find it very fishy to give these informations and was wondering if it was a legit thing or not? Specially that they threat to delete my account in the next 72hours which has now become 48hours, since I received this email yesterday. It was sent by ''Email address removed for privacy**". Got no clue what it is.  Please help me I am very concerned!
