Most (if not all) Federal Government employees, through an arrangement between Microsoft and your specific employment agency, are eligible to order a licensed copy of the select Microsoft Office desktop programs (which happens to include MSOXP ) you use at work to install and use on a home computer, for a VERY minimal fee & shipment. I recommend you check your agency/unit homepage and representatives for the link to the access/pin authorization code and information.
