Microsoft Outlook or Outlook (full name Microsoft Office Outlook since Outlook 2003) is a personal information manager from Microsoft, and is part of the Microsoft Office suite.
Although often used mainly as an e-mail application, it also provides a calendar, task and contact management, note taking, a journal and web browsing.
It can be used as a stand-alone application, but can also operate in conjunction with Microsoft Exchange Server to provide enhanced functions for multiple users in an organization, such as shared mailboxes and calendars, public folders and meeting time allocation.
Outlook replaced Microsoft's previous scheduling and mail program, Schedule+ and Exchange Client.
