Availability of clustered service

Failover behavior is configurable via the Failover Cluster Management application. If the service stops, the cluster either restarts the service or moves the ownership to another cluster node and starts the service from there. By default, service can restart twice within six hours before the failover occurs.

For Message Connector, the failover takes about two to three minutes. During failover, no HTTP or SMTP connections are accepted. After a failover, clients can again access the Message Connector, using the same name and IP address. Configuration and stored messages are available as before. The list of POP3 mailboxes must be explicitly reloaded (this is done by KC Plug-In).
