Proxying is used for Outlook Web App, Exchange ActiveSync, and Exchange Web Services

Redirection is used only for Outlook Web App

Deployment Options for a Client Access Server

Client Access servers:

Must be deployed in each Active Directory site that has Mailbox servers

Must have a fast connection to Mailbox servers and domain controllers

Need to be accessible from the Internet using the client protocol in Internet-facing sites

You can deploy Client Access servers:

On a single server with other Exchange Server roles

On a dedicated server to provide scalability

On multiple dedicated servers in an array

• Digest authentication

• Basic authentication

• Forms-based authentication

Protect the server with an application layer firewall

Considerations for Implementing Client Access Server Certificates

When implementing Client Access certificates, consider:

Whether to use an internal or public CA

The client access protocols in use

The server names used by messaging clients

Lab Scenario

You are working as a messaging administrator in A. Datum Corporation. Your organization has decided to deploy Client Access Servers so that the servers are accessible from the Internet for a variety of messaging clients. To ensure that the deployment is as secure as possible, you must secure the Client Access server, and configure a certificate on the server that will support the messaging client connections. You also need to configure the server to support Outlook Anywhere connections.

Lab Review

• In this lab, you configured the Client Access server to use a certificate from an internal CA. How would the steps change if you used a public CA?

• How would the steps in the lab change if you had two company locations, and you had to configure Client Access server access to both locations?
