Snippet from Wikipedia: Microsoft Outlook

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Primarily an email application, it also includes a calendar, task manager, contact manager, note taking, journal, and web browsing.

It can be used as a stand-alone application, or can work with Microsoft Exchange Server and Microsoft SharePoint Server for multiple users in an organization, such as shared mailboxes and calendars, Exchange public folders, SharePoint lists, and meeting schedules. Microsoft has also released mobile applications for most mobile platforms, including iOS and Android. Developers can also create their own custom software that works with Outlook and Office components using Microsoft Visual Studio. In addition, Windows Phone devices can synchronize almost all Outlook data to Outlook Mobile.
