All my folders on hotmail have not transferred to outlook. How can I retrieve them. They were there last week on Hotmail. very upset about losing them

I logged into hotmail okay on Wednesday 7 August 2013. was unable to access my emails on Thursday. Was told my password was nor known yet it was okay. Finally I convinced them I was genuine after giving details of recent email subjects, some email addresses I have contacted and names of some of my folders. Now luckily I do have my friends' email addresses but all my folders have gone. They did not transfer. How can I retrieve them/ I feel really fed up about this.
