The Microsoft Exchange Replication Service encountered an error while attempting to start a replication instance for %1. The specific error code returned is: %2.

This Error event indicates that the Microsoft® Exchange Replication (MSExchangeRepl) service encountered an invalid configuration. The Exchange Replication service starts an instance where it checks for invalid configurations. The event may be generated by the following conditions:

• The source and the destination paths to log files or system files do not point to the correct locations.

• Paths point to disks that are not mounted.

• The Microsoft Exchange Replication service cannot read from the cluster database.

For more information, see the following topics:

• Local Continuous Replication.

• Cluster Continuous Replication.

• Single Copy Clusters.

To resolve the error, follow one or more of these steps:

• Check the error description of the event and follow the steps that are required based on the specific error. For example, if the error indicates that the source or destination path is incorrect, fix the path.

• If the Microsoft Exchange Replication service cannot read from the cluster database, use the Services snap-in to check whether the Cluster Service is running.
