Xobni is “inbox” in reverse, but this free Outlook plugin is anything but backward.

Once you install, your Xobni dashboard appears in your inbox. When you get an email, you see all kinds of fun facts, such as the email conversations you’ve exchanged, the times of the day that your contact usually sends emails, the other people who have been included in your conversation. Plus all the attachments you’ve exchanged are listed together.

There are plenty of other little tricks, but my favorite feature is a simple one. How many times have you gotten an email about a meeting and had to switch to your calendar to check availability? You have to switch back and forth between the inbox and the calendar, cutting and pasting phone numbers, figuring out meeting times, etc. But when you switch to the calendar, Xobni keeps the last email you viewed in the dashboard. No more flipping back and forth.
