I have a new exchange 2010 server I am testing on our network which already has a 2003 exchange server. I was testing another 2010 exchange box on the netwoek about 6 months ago but was not able to gracefully remove it from the network.
I have done my best to remove all traces of it from AD using such tools as ADSIedit.
I have been testing the new server and have found that it will not deliver mail externally. Using the mail flow trouble shooter I get this error.
MSExchangeTransport' Event ID 5006 was found on MyNewEXCH2010svr at TIMEWRITTEN with description 'Cannot find route to Mailbox Server CN=OLD_2010svr\0ADEL:1753693b-f8e7-4e41-a5af-4df1b94e1e1e,CN=Servers\0ADEL:5d8c3cfd-0e37-4a64-9018-307d191ccc93,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=MyDOMAIN,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=MyDOMAIN,DC=com for store CN=Public Folder Database OLD_2010svr,CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=MyDOMAIN,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=MyDOMAIN,DC=com in routing tables with timestamp 9/28/2011 6:43:09 AM. Recipients will not be routed to this store.'.
For some reason this error is still referring to this other 2010 exchange box I have 'cleaned' out of AD. So I am not sure where to look now to clear out these old references since I have scoured all the usual areas in adsiedit (like what is designated in the error).
All help gratefully received.
