Examine the contents of the routing table logs and view the data in the ADTopologyPath ID section to verify that the selected site exists along the least cost routing path between two Active Directory sites. If this isn't the case, you need to assign Exchange-specific costs to the IP site links to make the least cost routing path go through the selected sites. For detailed steps, see Set an Exchange Cost on an Active Directory IP Site Link.
