DescriptionThe ADC cannot replicate <object name> because it does not have a legacyExchangeDN for the site it belongs in. <connection agreement name>
Event InformationAccording to Microsoft:
EXPLANATION:
This event indicates that the Active Directory Connector (ADC) is not replicating an object found in Active Directory to the Exchange site because the LegacyExchangeDN attribute is not stamped on the object in Active Directory. This can occur if the Create objects in location specified by Exchange 5.5 DN check box is selected on the FROM WINDOWS tab of the connection agreement. This option is used to prevent the creation (in the Exchange 5.5 Directory) of sub-containers in Active Directory.
USER ACTION:
Clear the Create objects in location specified by Exchange 5.5 DN check box on the properties of the connection agreement in question. You may have to examine WHY this option was set in the first place.
