Event InformationAccording to Microsoft :
Cause :
This Error event may be triggered by multiple causes. Similarly, the method by which you resolve this error varies greatly depending on what triggered this event in the particular Microsoft Exchange environment. This error is generated while the System Attendant is in the data gathering phase. Data gathering consists of reading Active Directory for the Distinguished Name of the Offline Address List, determining the version number, and determining whether to write to disk or Public Folder. This failure occurs before any attempt to generate the Offline Address List.
Resolution :
To resolve this error, do one of more of the following:
1.Review the System and Application event logs for related events. For example, events that occur immediately before and after this event may provide more information about the root cause of this error.
2.At this point, an error will most likely require debugging the Microsoft Exchange System Attendant process.
Note :
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.
