|Message:||The Active Directory site for Exchange server %1 was not determined in routing tables with timestamp %2. Recipients will not be routed to this server.|
This Error event indicates that the Microsoft Exchange Server 2007 transport routing engine can’t determine the Active Directory directory service site membership for the specified Exchange server. Routing has determined that a message should be delivered to the indicated server. However, the Active Directory site information for this server is not available in the referenced routing table. Therefore, routing is unable to deliver messages to recipients with mailboxes located on this server. This error may be caused by Active Directory replication latency.
