Xobni - A Outlook add in

After a quick install, you'll see the new Xobni toolbar appear in Outlook - and suddenly information will become much easier to find. When a new email arrives, the sender's full communication history appears in the Xobni sidebar, including past conversations, attachments and contact details. Xobni also includes a blazing fast email search tool.
You can download the add in for free.
