Am I able to up/cross-grade from the Personal Edition to Home or Business Edition

I purchased the Personal edition back in Nov & didn't realise I wasn't getting Outlook.
I now need Outlook & would like to up/cross-grade. I cannot see how I can do that. Is it possible at all?
& If so, how?

Warm Regards
