I downloaded the Windows Live bundle from http://home.live.com and liked the outlook connector in there. It is pretty cool and allows one to integrate various non-corporate e-mail accounts into your outlook.
This provides for a richer experience. See below.
I can read my office e-mail and as well as other mail from services such as hotmail in one client, which provides a richer experience. As you can see I have my main office e-mail which is expanded and as well as my various hotmail accounts all in one place. The bottom three (Red Arrows) are all my various hotmail accounts.
Not only that you can see side by side the calendar entries. See below – I think this is really cool, where I can see my office calendar and as well as my personal or private calendar. I prefer to keep these separate.
