Synchronising Live Mail Accounts

After upgrading my desktop computer to Vista Ultimate I've installed Live
Mail because it runs on both Win XP and Windows Vista machines. My laptop
runs Win XP pro and I am looking for a way to synchronise the Live Mail
folders on both machines.

I have imported all old Outlook Express emails (the desktop was running
Windows 2000) into Live Mail but the folder and file structures on the
laptop and the desktop pc differ.

Would it be possible to simply copy all files from the desktop Live Mail
folder to the laptop Live Mail folder or is there another way to synchronise
both?

Thanks a lot in advance
Joerg
