Outlook Web App - Uses

Uses

Outlook Web App is used to access e-mail (including support for S/MIME), calendars, contacts, tasks, documents (used with SharePoint or in 2010, Office Web Apps), and other mailbox content when access to the Microsoft Outlook desktop application is unavailable. In the Exchange 2007 release, OWA also offers read-only access to documents stored in Microsoft SharePoint sites and network (UNC) shares. Microsoft provides Outlook Web App as part of Exchange Server to allow users to connect remotely via a web browser. Some of the functionality in Outlook is also available in this web "look-alike". The most important difference is that Microsoft Outlook allows users to work with e-mail, calendars, etc., even when an internet connection is unavailable, whereas OWA requires an internet connection to function.

Outlook Web App also is used to function on Microsoft Office 365, with use of Microsoft Lync and SharePoint document sharing.
