Did you create the send connector on Exchange 2007? Is it using a SmartHost or DNS? what is the cost of the send connector? If it is greater then the Exchagen 2000 send connector it will not go out through Exchange 2007. What about the RGC between 2007 and 2000? Did you allow the Hub Transport server the ability to send outside the org through the firewall if one is in place? BP

hi,did you make your exchange server 2007 master in the routing groups - first routing group - members.there must be all of your exchange servers here. and please assign master role to your Exchange Server 2007 and then try again to send mail from exchange server 2007.regardsExchange - MVP | www.cozumpark.com | www.mumincicek.com

Issue description: Mail cant be sent externally Check info: 1. Please describe more details of exchange topology 2. Does the internal mail flow work normally between exchange 2000 and exchange 2007? 3. Can the mail be sent from internet to exchange? Please try to telnet for testing 4. Is there any NDR generated if the message has failed to deliver? 5. Please use message tracking to monitor the test message, see the NDR is generated on which server. If the test mail stuck in the queue, please use queue viewer to check the message 6. Please use Mail Flow Troubleshooter to troubleshoot the issue Resources: Message Routing in a Coexistence Environment Coexisting with Exchange Server 2003 and Exchange 2000 Server

Hi, Visit the URL below for the screenshots you need on creating a send connector bound to internet. http://www.petri.co.il/configuring-exchange-2007-send-connectors.htm Just make sure you know who will route your emails (Example: Appliance/Software base SMTP GATEWAY, ISP/DNS/MX, Edge Transport Server). regards, LRMCP
