This might probably be the silliest email lottery scam you have ever seen. Just look at the circled email id of the sender. Now why will Microsoft have a Lottery Scheme and have the reply address to a yahoo account. The sender should have made a little more effort in using a Microsoft email id to send such mail if he ever wanted to get some result. Com on dude, think before you send something like this around. Have a look and see for yourself and tell me what you think.
