Need to Copy Emails in Outlook Express on to CD ASAP

I have to format my hard drive tonight. I’m copying important info onto CD’s. I can’t figure out how to copy the emails. I save them for business purposes and need them. Can anyone tell me how? I have to stay up all night until I figure it out, a satellite internet service is being hooked up tomorrow and I’ve got to get my computer up to par.
