It can integrate tightly with your system contacts by displaying names and photos. There are also options to indicate unknown senders and auto-save message recipients in your phone's contact list. Furthermore, the app will provide you with a suggestions list of e-mail addresses you've received or sent mail to recently.
The Calendar synchronization for Exchange and Office 365 gives you immediate access to your scheduled events. It is completely compatible with any calendar app or widget.
