Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. The current versions are Microsoft Office Outlook 2013 for Windows and Microsoft Office Outlook 2011 for Mac.
Although often used mainly as 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. There are third-party add-on applications that integrate Outlook with devices such as BlackBerry mobile phones and with other software such as Office and Skype internet communication. Developers can also create their own custom software that works with Outlook and Office components using Microsoft Visual Studio. In addition, Windows Mobile devices can synchronize almost all Outlook data to Outlook Mobile.
