Outlook Web App
Applies to: Exchange Server 2013
Learn about the Outlook Web App, which was called Outlook Web Access in versions of Microsoft Exchange earlier than 2010. This article provides a brief overview with links out to helpful information.
By default, when you install Microsoft Exchange 2013, you enable Outlook Web App. Microsoft Outlook Web App lets users access their Exchange mailbox from almost any Web browser.
The Client Access server role provides proxy and redirection services for Outlook Web App.
Overview of Outlook Web App
Fully supported web browsers give users access to features such as conversation view, Inbox rules, the reading pane, and the Scheduling Assistant. Browsers that aren't fully supported can still be used, but users will see the light version of Outlook Web App, which has fewer features. For information about new features in Outlook Web App, see What's new for Outlook Web App in Exchange 2013.
Managing Outlook Web App
In Exchange 2013, the most common Outlook Web App management tasks can be accomplished in the Exchange admin center (EAC). All these tasks, and many others, can be accomplished by using the Exchange Management Shell. You'll still use tools such as Internet Information Services (IIS) Manager for some tasks, for example, to configure Secure Sockets Layer (SSL) or set up simple URLs for users.
Accessing Outlook Web App
You and your users can sign into Outlook Web App using a URL like this: https://<domain name>/OWA or https://mail.<domain name>/OWA
If, for example, your organization's domain is contoso.com, then use https://contoso.com/OWA or https://mail.contoso.com/OWA. Learn more about accessing Outlook Web App here. To change the sign-in URL to something different or to force redirection to SSL, see Simplify the Outlook Web App URL.
