Configuring the Exchange Server 2007 Client Access Server

Last week we looked at how to plan for an Exchange Server 2007 transition, how to prepare and install a new server to host Exchange Server 2007, and how to install the first Exchange Server 2007 server in the organization.  This week we continue with configuring the new Exchange server roles, starting with the Client Access Server.

Open the Exchange Management Console and navigate to Server Configuration/Client Access.

Configure Outlook Web Access

Before Outlook Web Access is published to the internet you must enter the external URL.  Open the properties of the owa (Default Web Site) and enter the external URL in the field shown here.

If you are publishing via ISA Server select the Authentication tab and choose Use one or more standard authentication methods, setting it to Integrated Authentication and Basic Authentication.

Click OK when complete.  A warning will appear that the changes will not take effect until IIS is restarted.

Click OK but don’t worry about restarting IIS yet, we’ll be restarting it soon.

Configure ActiveSync

Similar to Outlook Web Access the ActiveSync external URL must be configured if it is being published to the internet.  Choose the Exchange ActiveSync tab and then open the properties of Microsoft-Server-ActiveSync.

Enter the external URL in the field shown here.

Click OK when complete.

Configure Outlook Anywhere

In the Actions pane to the right of the Exchange Management Console click on Enable Outlook Anywhere.

Enter the external host name in the field shown here.

If you are publishing via an ISA Server on the same external IP address as Outlook Web Access then choose Basic Authentication.  If you can dedicate an external IP address for publishing Outlook Anywhere then choose NTLM Authentication.

Click Enable when complete.  You will receive a warning that Outlook Anywhere will not be available for up to 15 minutes.  Click Finish to clear that warning.
