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

Exchange setup requires that Exchange Server roles be installed to a drive that is not a shared cluster resource.

To resolve this issue, install the Mailbox server role or cluster Mailbox server to a path that is not designated as a shared cluster drive.

For more information about clustering configurations, see "High Availability" ( in the Exchange Server 2007 product documentation.
