Can you give us more information about the task? Do you actually want to automate Outlook or are you just trying to read (and process) mail stored on the exchange server? Using Super Search will find you examples using modules such as Mail::Box, Mail::Outlook and other for automating email processing.
Have you considered simply changing line 10 to point to a module which actually exists?
use Win32::OLE::Const 'Microsoft Outlook';
N.B. you will have to install this module if your Perl ditribution doesn't already have it.
