Unable to create a folder inside folder in Windows Live Mail

Original title: creating folders in folders win 8

hey all

im changing email address' and trying to move my old messages to my new account, but the outlook.com account wont let me put folders in folders???

could it be that bigpond is still default, or is it just a outlook.com thing, no folders in folders, ever.

i dont want to loose my emails experimenting.

in bigpond... bank, phone, computer, etc all hide inside barry

in outlook... i get, Note: You cannot create a folder inside this folder

i really dont want twenty plus folders all spaced out down that side.

any help

thanks.
