Copy Files and Folder in old computer with the Same Configuration

I’m having problems regarding Microsoft Office.
The drive which I previously used in my computer is now in another computer working as a slave drive.
I’ve recently installed Microsoft Office, the same one as to the one in my old computer.
Now, what should I do to get the files in my old Microsoft Office?
Is there another way like copying key files and folders, and setting it to the same configuration the same one in my old Microsoft Outlook?
Thanks to those who can help.
