I have a hotmail.com account that automatically switched to outlook.com recently.  I need to set up a new email address and transfer old email files to it.  I don't have a clue how to do it and not loose my old email account files.  I do not want any new messages to be received in the old hotmail.com account once I set up a new one.  Is there anyway to alert senders that they need to resend to new address as well?
