Hi community.

At the start of 2015, I bought myself a Macbook and MS Office 2011 to go along with it. I installed it that night but i deleted the things that I know i would not use to save space, a pretty stupid thing to do now that I'm thinking back. One of the things that i deleted was the email client Outlook. 

I would now quite like to get this program back onto my Macbook but i reckon I'd have to uninstall then reinstall the whole package. The only problem that i have with that is i do not know where my product key is. Is there a way can can find it online or request a new one in anyway?

Thanks for any help.
