[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine the value for the msExchESEParamBaseName attribute of all objects with a class of msExchStorageGroup. Objects with this class are storage group objects. A value of R00 for the msExchESEParamBaseName attribute indicates that the storage group object is a recovery storage group. If the Exchange Server Analyzer finds that the value for this attribute is R00, a warning is displayed.

This warning indicates that a recovery storage group exists. We recommend that you remove a recovery storage group after you complete the recovery process. If you do not remove a recovery storage group, an administrator who is unfamiliar with recovery storage groups may be confused when performing a standard recovery in the future.

  1. Open Exchange System Manager.

  2. Expand Servers, and then expand the server that contains the recovery storage group you want to delete.

  3. Right-click the recovery storage group, and then click Delete.

  4. Close Exchange System Manager.
