This Warning event indicates that an exception occurred when trying to validate the Exchange topology configuration data that is to be replicated to the Active Directory Application Mode (ADAM) instance on the computer that is running the Edge Transport server role. The configuration data must pass validation before the computer that is running the Hub Transport server role can start synchronization. EdgeSync must be able to acquire current Exchange topology data from Active Directory to correctly operate. The exception specified in the event description provides more information about this failure.
This may be caused by an error detected in the schema on one of the Edge Transport servers. For example, this event may be logged if Hub Transport servers in your organization are running different versions of Exchange.
To resolve this warning, make sure that all your Hub Transport servers are running the same version of Exchange 2007.
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.
