Outlook Express messages

I just installed a new hard drive With 98Se. I was not able to get both drives working in the machine at the same time, so I could not clone the drives. The original drive was starting to fail.

Is there anyway to take the messages from the old drive and get them into the new drive? I tried to do an Export, but it would only look for a new version of Outlook Express or Outlook. I have the old drive and am able to install it in an old system.

Any any ideas?
