I have Outlook 2010 installed on my Desktop
I also have it installed on my laptop from work.
I am about to install it on my personal laptop.
I also have a notebook which I like to use when I'm out and about or in front of the TV.

What I want to do is to sync them all up. I want to use my Desktop as the main place of where I can store everything on. But I want to make changes etc on my laptops and notebook.

I don't want to pay ridiculous amounts of money for the software, but I was hoping that there maybe a addon or a plugin which would allow me to do all of this?
