Enable and configure Outlook Anywhere

Outlook Anywhere on all of the Exchange 2007 and Exchange 2010 servers in your organization. If some Exchange 2007 or Exchange 2010 servers in your organization are already configured to use Outlook Anywhere, their configuration must also be updated to support Exchange 2013. When you use the steps below to configure Outlook Anywhere, the following configuration is set on each Exchange 2007 and Exchange 2010 server:
The Outlook Anywhere external URL is set to the external hostname of the Exchange 2013 server.
Client authentication, which is used to allow clients like Outlook 2013 to authenticate with Exchange, is set to Basic.
Internet Information Services (IIS) authentication, which is used to allow Exchange servers to communicate, set to NTLM and Basic.
