Outlook Anywhere

What is Outlook Anywhere?

This is a system that lets you connect Microsoft Outlook to to your Exchange server over the web, this means you can connect to to your email, calendaring and tasks etc, without the need for a VPN connection.

Outlook Anywhere wizard on the Exchange Server 2010 Client Access server to allow users to connect to their Exchange mailbox from the Internet. Outlook Anywhere eliminates the need for users in remote offices or mobile users to use a virtual private network (VPN) to connect to their Exchange servers.
Outlook Anywhere will be enabled on your Client Access server after a configuration period of approximately 15 minutes. To verify that Outlook Anywhere has been enabled, check the application event log on the Client Access server

The Windows RPC over HTTP Proxy component, which Outlook Anywhere clients use to connect, wraps remote procedure calls (RPCs) with an HTTP layer. This allows traffic to traverse network firewalls without requiring RPC ports to be opened. In Exchange 2010, as in Exchange 2007, it's easy to deploy and manage this feature. To deploy Outlook Anywhere in your Exchange 2010 messaging environment, you need to enable Outlook Anywhere on at least one Client Access server using the Enable Outlook Anywhere wizard in the Exchange Management Console

 Install a valid Secure Sockets Layer (SSL) certificate from a certification authority (CA) that the client trusts.
Install the Microsoft Windows RPC over HTTP Proxy component if it wasn't already installed by default in Windows Server 2008. For detailed steps, see Install the Windows RPC Over HTTP Proxy Component.
