I would like to know how this will affect me if I drop the service.

I do not utilize the service at all, Therefore, my concerns all have to do with my email. It looks like I will still have the same email address which is fantastic.

I tried to see how much space I have used in my email but I can't find that answer anywhere.  I do not want to lose anything in my email. It looks like with outlook you get 15gb free. It looks like with MSN you get up to 10gb, however, I don't know how much email I have used.
