Importing messages from Outlook Express to Outlook

I'm importing my messages and accounts from Outlook Express 5 to Outlook 2000. Apparently, the messages import fine, but I have custom folders setup and I can't find them (all I see are the messages in my inbox and not the ones I refiled nor the ones in my outbox.

Is there something I need to do in order to see them?

Click on the down arrow on your folder banner, (just above from, to, subject, received...), and you should see all your folders.
