Outlook Permissions

I’ve got Outlook 2000 on a Win 2000 laptop & Desktop. The Desktop has the most current Outlook files and I want to transfer it’s files via my Ethernet network to the laptop. After having done so the Laptop won’t permit me to access the files saying I don’t have permission to access the files. I’ve read the Help messages in an attempt to find out how to change the permissions to read them, but nothing seems to work. Any suggestions?
