|Message:||The MTA was unable to route to recipient <recipient>. The message (MTS-ID): <message id>, recipient: <recipient>, recipient number <value>. Check the routing table for a possible incorrect routing configuration. [<value> <value> <value> <value>] (12)|
The message transfer agent (MTA) was unable to route to recipient.
In Exchange 2000, the MTA uses the Routing Engine service to route messages. Try to stop and restart the routing engine, checking the event logs for errors. It may be necessary to use Winroute to view the routing tables.
