User Action

To resolve this error, depending on the error returned in the error text, perform one or more of the following:

  • Verify that the version of Microsoft Exchange that you are using is compatible with the database version that you are trying to mount. If they are not compatible, try to mount the database on a server that is running the correct version of Exchange.

  • Review the Application log for related events that might indicate if the database is corrupted or not. If the database is corrupted, restore the database from backup to a known good state. If you cannot restore the database, contact Microsoft Product Support Services for assistance running the Information Store Integrity Checker (Isinteg.exe) tool.

  • If this error is the result of an upgrade that failed, try to upgrade the database again.

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.
