Thunderbird:

Even though with the persistence of the fact that the Outlook is the best and it cannot be replaced,some slight tweaks and a little bit of add-ons or plugins can make Outlook look like a past story. With the addition of two plugins- Exquilla and Lightning Exchange Provider, it is now possible to connect with the user’s personal Exchange server. This setup can be marked as a very business- friendly, enterprise- ready email system.
