Only One CCR Server Allowed
Topic Last Modified: 2007-03-27
Microsoft Exchange Server 2007 setup cannot continue because the attempt to create a new cluster mailbox server failed.
Exchange Server 2007 requires that only one cluster continuous replication cluster mailbox server exist in the cluster continuous replication (CCR) cluster. A cluster mailbox server already exists in this CCR cluster.
To resolve this issue, do not attempt to install an additional cluster continuous replication cluster mailbox server in this cluster.
For more information about installing the cluster mailbox server in a CCR environment, see "How to Install the Mailbox Server Role on the Active Node" (http://go.microsoft.com/fwlink/?LinkId=86624) in the Exchange Server 2007 product documentation.
