Offline Folders

I have a user setup up on a laptop (Win2k,Outlook 2k). The computer was setup up to allow offline access to exchange folder when he traveled. Recently I had moved the mailbox over to the new Exchange 2000 server and now the offline functions no longer work.
I have deleted the profile and set it up again and selecting yes to “do you travel with this computer” which is all I had done before to make it work. Now when I open outlook in an offline status I get “do you want to open the default folders” basically local hard drive folders.

I am still in the middle of the Exchange 2k upgrade. All mailboxes are on the new server but The exchange 5.5 computer is still online and processing the email.
Any ideas?????
