I just installed the Xobni plugin for MS Outlook, and it’s amazing. It gives me stats such as how many emails I send and receive by hour, by person, median time to respond and many more stats. Even if you aren’t interested in all that stuff, install it because it adds search capabilities that destroy Outlook’s offering (aka, you can find relevant emails to your search!). I’ve literally only been using this plug-in for only 30 minutes, but it’s already made Outlook that much more tolerable. Definitely try it out if you’re looking for a better Outlook experience.
