You must have access to your product key to reinstall whichever Outlook version you have. If you downloaded Outlook from Microsoft's website, then you must have got the product key in your email. If you have misplaced the product key and are unable to find it, download an automatic (free or paid) tool from a trusted website to find out the product key. It is recommended that you download such program from only trusted websites in order to avoid carrying virus infections into your computer. Usually, product key is printed on the back or inside of the CD case.
