Microsoft Exchange Server 2007 setup cannot continue because the attempt to install the clustered Mailbox server role to a shared cluster drive failed.

Exchange setup was unable to write to the target install path submitted for the /CMSDataPath parameter. Exchange setup requires that the target path for the clustered mailbox server data be a writable volume.

To resolve this issue, specify a target path for the /CMSDataPath that is on writable storage media.

For more information about installing the clustered mailbox server, see "How to Install the Mailbox Server Role on the Active Node" ( in the Exchange Server 2007 product documentation.
