|Message:||The Microsoft Exchange Replication Service VSS writer initialization failed with error code %1. The Exchange VSS writer is not loaded.|
This Error event indicates that the writer of the Volume Shadow Copy Service (VSS) of the Microsoft® Exchange Replication service did not initialize. The VSS writer is initialized during Microsoft Exchange Replication service startup. This writer enables the replication service to take VSS-based backups of replica copies in the cluster continuous replication (CCR) and local continuous replication (LCR) environments. This failure will not result in a failure of the replication service. Because of this error, VSS backups of the replica copies will not be made.
To resolve the error, stop and start the Microsoft Exchange Replication service from the Services snap-in to initialize the VSS writer.
If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
