We had an exchange 2003 server which is now decommissioned. Exchange is still installed but no exchange services are running on it. We are running a new Exchange 2007 server. Event viewer shows event id 5016 "Could not discover route to [old exchange 2003 server]".
On Exchange 2007 server, I select hub transport then the send connectors tab. There is an entry entitled "router to [old exchange 2003 server]". It is routing mail through smart host [new exchange 2007 server]. However, source server is [old exchange 2003 server]. I am guessing that this entry is causing the event viewer error.
I tried to disable this entry and received the following error.
Action 'Disable' could not be performed on object 'router to exchange'.
router to exchange
Property Enabled cannot be set on this object because it requires the object to have version 0.1 (8.0.535.0) or later. Current version of the object is 0.0 (6.5.6500.0).
I want to disable this entry rather than outright removing it because I want to monitor the effects that is has, if any, on mail flow.
Any suggestions would be greatly appreciated.
