How to transfer my emails from a hotmail account to another one?

I need to transfer my emails from a hotmail account (with all folders included) to another hotmail account also.

I have added both of the accounts to Windows Live Mail.

When I tried the Export mails - Import mails method included here:
http://windows.microsoft.com/en-us/windows-live/mail-import-backup-restore
I got the mails in storage folders, but it did not appear in my second account when I open it without the Windows Live Mail.

I found some people here say I can drag and drop the mails easily between the accounts from Windows Live Mail, but I do not know how.
