Question about Outlook Express

The hacker was able to see my word documents, used the same font and format I use, copy and paste a signature to the letter sent to my broker.  The only thing the hacker lacked was my telephone numbers and account numbers.  I was told by the police and Equifax to immediately change my email to a different address.  I need to keep all my folders and contacts and want to stay with hotmail or outlook but am told transferring folders cannot be done.  Is there a way to do it or a way to change my login ID and keep the folders intact.  Please help as this is a serious problem and all of my contacts are getting the same email that spammed me.  Thank You.
