You can configure Integrated Windows authentication for Outlook Web App in Microsoft Exchange Server 2010. Integrated Windows authentication enables the server to authenticate users who are signed in to the network without prompting them for their user name and password and without transmitting information that isn't encrypted over the network.

Note:
Integrated Windows authentication can be set only on Exchange 2010 virtual directories on an Exchange 2010 server that has only the Client Access server role installed. Integrated Windows authentication can be set on any Outlook Web App virtual directory on an Exchange 2010 server that has both the Client Access and Mailbox server roles installed.
