Microsoft Exchange Server 2007 setup cannot continue to install the Client Access server role on the Microsoft Windows Server 2008-based system because the required Internet Information Server (IIS) 7 components are not installed.

Exchange 2007 setup requires that the Windows Server 2008-based computer where you are installing the Client Access server role has the following IIS 7 components installed before installing the Client Access server role.

Required IIS 7 Components

Windows Authentication

To address this issue, install the required IIS 7 component(s) to the destination computer, and then rerun Microsoft Exchange setup.

  3. On the Select Role Services pane, scroll down to IIS.

  5. Select the check boxes under Performance for Static Compression and Dynamic Compression.

  6. Click Next from the Select Role Services pane, and then click Install at the Confirm Installations Selections pane.
