I have tried signing into an old Hotmail account several times, when I try to I get this message ‘That Microsoft account doesn’t exist. Enter a different email address ‘

This is an account from about 3 years ago now but I would like to sign into it to reactivate some old social networking sites which I have some memories and pictures to on there I have send password resets to this email also which would help me do this if I could get in its only Hotmail that it 'Doesn't exist' with. I haven't heard of Hotmail ever deleting its accounts if they get old but even still if it was deleted for being so old then surely I wouldn't still be able to send password resets to it and sign into my Myspace using it. Please help!!!
