I have just installed my new 2k7 server. The 2k server still exists for the time being and is where mail is being delivered to from the outside. I have moved a mailbox to the 2k7 server, but it does not get any mail to it. It has its original mail, but nothing new sent into the organization makes it to the 2k7 server mailbox. Am I not understanding the connection between the servers, or is there an error my configuration? Any pointers on what to look for would be greatly appreciated. -Eric

Hi, When you installed the 2007 server it should have created a routing group connector between the 2 routing groups. Did this get created? - you can see it from the 2003 ESM. Can you see what happens to the mails for the 2007 mailbox? Leif

There is a Send Connector in the Hub Transport that has my old server's name, but the Site and Role fields are blank and "None" respectively. If I use Message Tracking on the original server, it says that it submits the mess to Categorizer, then Advanced Queing. It repeats this 3 times before generating an NDR. -Eric

Hi, What does the ndr say? This might help: http://blogs.3sharp.com/Blog/deving/archive/2007/03/06/2994.aspx Leif

The NDR says ... The following recipient(s) cannot be reached: Person on 7/22/2007 11:25 PM Could not deliver the message in the time limit specified. Please retry or contact your administrator. In reading that site, and taking a look at the configuration, it appears that I do not have a Legacy Routing Group Connector. -Eric

It is fixed, thanks for the link which pointed me in the direction of the issue. I issued the following command in the shell and now everything is working correctly. New-RoutingGroupConnector -Name "Interop RGC" -SourceTransportServers "Exchange2007Server" -TargetTransportServers "Exchange2000Server" -Cost 1 -Bidirectional $true -PublicFolderReferralsEnabled $true
