Microsoft Outlook is a personal information manager software framework that is included in the Microsoft Office suite. The outlook is mainly an email client, but it also has calendaring, task management, contact management, note-taking, journal logging, and web browsing capabilities.
Individuals can use Outlook as a standalone application, while companies can use it as multi-user software (via Microsoft Exchange Server or SharePoint) for items like mailboxes, schedules, directories, data aggregation (via SharePoint lists), and appointment scheduling. Microsoft has applications for iOS and Android, among other smartphone devices. Moreover, virtually all Outlook data will be synced to Outlook Mobile from Windows Phone devices. Developers can create custom software that works with Outlook and Office components using Microsoft Visual.
Outlook.com is a free webmail service that looks and feels like Microsoft Outlook. It was formerly known as Hotmail before being renamed Outlook.com in 2012.
Outlook on the web (formerly Exchange Web Link, Outlook Web Connection, and Outlook Web App) is a web-based business edition of Microsoft Outlook that comes with Office 365, Exchange Server, and Exchange Online.
Outlook has replaced Microsoft’s earlier scheduling and email clients, Schedule+ and Exchange Client.
There are two configurations available in Outlook 98 and Outlook 2000:
Internet Mail Only (also known as IMO mode) is a lighter application mode that focuses on POP3 and IMAP accounts, as well as a lightweight Fax application. Corporate Workgroup mode (also known as CW mode) is a complete MAPI client that focuses on Microsoft Exchange accounts.
