all that info is in a .pst-file (or some other local file) that isn't deleted by the uninstall. But to be sure you could make a backup of that information. Of course, when you really go to use the software in stead of just trying it, it's essential you make a regular backup so any time spent to find out how to do it, and how to restore the data, is well-spent.

It seems rather easy, in fact:
