Office applications missing in Automator Library

Hi there,

I am new to the Automator and was looking to build a new service using Outlook. I wanted to be able to select a file and send it as attachment using Outlook via the services menu.

But I am unable to find Outlook or any other MS Office objects in the Library of Automator. Screenshot attached. 

Is there a trick to add them into automator options? Thanks

Loukik.
