Create A Routing Group Connector Between Exchange 2003 and Exchange 2010

IT Problem

I recentley had to add an exchange 2010 server into a 2003 organization. As part of the installation a routing group connector is created but for some reason it was not created correctly created. Here is how to create a routing group connector in powershell from exchange 2003 to exchange 2010

IT Solution

So first run the exchange 2010 power shell . Once you are in the exchange powershell copy and paste the command below making changes the the server names.

New-RoutingGroupConnector -Name “RGC 2003-2010″ -SourceTransportServers “exchange2010server.yourdomain.local” -TargetTransportServers “exchange2003server.yourdomain.local” -Cost 100 -Bidirectional $true

New-RoutingGroupConnector -Name “RGC 2003-2010″ -SourceTransportServers “exchange2010server.yourdomain.local” -TargetTransportServers “exchange2003server.yourdomain.local” -Cost 100 -Bidirectional $true

Ok so replace exchange2010server.yourdomain.local with the FQDN of your exchange2010 server and also replace exchange2003server.yourdomain.local with the FQDN of your exchange 2003 server.

Then on the 2003 server, restart the smtpSMTP or Simple Mail Transfer ProtocolSMTP or Simple Mail Transfer Protocol is a protocol used to send Email over the internet.SMTP runs on port 25 and it its most basic form uses three command/reply sequences.MAIL, RCPT and Data.So an email client sends an email to another client by connecting to the SMTP server of a company which then sends the email to another companies SMTP server which inturn sends the email to the local client. is a protocol used to send Email over the internet.SMTP runs on port 25 and it its most basic form uses three command/reply sequences.MAIL, RCPT and Data.So an email client sends an email to another client by connecting to the SMTP server of a company which then sends the email to another companies SMTP server which inturn sends the email to the local client. service and then on the exchange 2010 server restart your exchange transport serviceThe Microsoft Exchange Transport service is an SMTPSMTP or Simple Mail Transfer Protocol is a protocol used to send Email over the internet.SMTP runs on port 25 and it its most basic form uses three command/reply sequences.MAIL, RCPT and Data.So an email client sends an email to another client by connecting to the SMTP server of a company which then sends the email to another companies SMTP server which inturn sends the email to the local client. service in Exchange Server 2007 and Exchange 2010 onwards which controls mailflow in and out of your exchange system. This service will only run in the Exchange Active Directory Topology Service is running..

The connector is bi-directional so mail will now flow both ways.
