Learn about administrative tasks for managing Outlook on the web (Outlook Web App) in Exchange 2016.
The user interface in Outlook on the web (formerly known as Outlook Web App) for Exchange Server 2016 has been optimized and simplified for use with phones and tablets. Supported web browsers give users access to more Outlook features. Unsupported web browsers give users the light version of Outlook on the web that has less features. For more information about features and supported web browsers, see What's new in Outlook on the web: Upgrading from Exchange 2013 to Exchange 2016 and What's new in Outlook on the web: Upgrading from Exchange 2010 to Exchange 2016.
When you install Exchange 2016, Outlook on the web is automatically available for internal users at
https://<ServerName>/owa (for example,
https://mailbox01.contoso.com/owa). But, you'll likely want to configure Outlook on the web for external access (for example,
https://mail.contoso.com/owa). For more information, see Configure external URLs.
In an Outlook 2010 or later installation that's connected to an Exchange mailbox, you can typically see the Outlook on the web URL at File > Info > Account Information in the Account Settings section.
Outlook on the web is provided by the Client Access (frontend) services on Mailbox servers. In Exchange 2016, Client Access services are part of the Mailbox server, so you can't configure a standalone Client Access server like you could in previous versions of Exchange. For more information, see Client access protocol architecture.
