This email client has a sleek design and is optimized for Exchange, Office 365, and Outlook.com. It includes a calendar, task manager, and contact integration. It is lighter than Outlook and has unique features.

One of the key advantages of this email client is that it comes with fully integrated calendar, tasks and contacts features, making it easy to keep all your important information in one place. Additionally, it has been specifically built to work seamlessly with Exchange, Office 365 and Outlook.com, using Microsoft's own protocol - EWS. This means that if you ever need to go back to Outlook, everything will still be synced up and you won't lose any data.
Some of the other nice features of this email client that I really appreciated include a great task list built-in, which lets you drag an email to the right-hand side to easily create a to-do item out of it. The search function is incredibly fast, and you can also triage your emails using the Action/FYI filters. Furthermore, you can deal with your emails using the 4 D's - Defer, Delete, Delegate and Do - which makes managing your inbox much simpler.
Another unique feature of this email client is the ability to send emails with actions attached, and there is even a dashboard and timer that remind you not to check your email too often - a really bad habit that many of us fall into! Lastly, I appreciated the clever touch of having the subject line at the bottom of the compose window. This encourages you to write a better subject line after you've already written the email, which can help your emails to stand out and get noticed.
Overall, I believe that this email client is a fantastic choice for anyone looking for a lightweight and feature-packed email software. Its unique features and fast performance make it a great alternative to Microsoft Outlook.
