Exchange 2010 cannot send or receive internal mail

Hi,

I think you should verify the permissions "Routing group connectors" & test the connector is used for one-way or two-way mail flow New-RoutingGroupConnector

you would need to create additional routing connector, Please refer the below command and its referenced article also

New-RoutingGroupConnector -Name "Interop RGC" -SourceTransportServers "Ex2010Hub1.contoso.com" -TargetTransportServers "Ex2003BH1.contoso.com" -Cost 10 -Bidirectional $true

Dear Both,

I did use new-routinggroupconnector to create two-way mail flow, but still cannot send/recevive email for internal

For smooth mailflow between Exchange 2003 & Exchange 2010 there should be routing group connector between 2003 to 2010 and vice versa.

Also ensure you can successfully telnet both the servers from another one.

Tahir

Please restart the "Routing Engine" service in Exchange 2003 and try to telnet also

Dear Sir,

I can telnet from both side without issue

Ihave no communication in Default SMTP Virtual Server

below is the report

Could you please confirm, did you restarted the routing engine service in exchange 2003, if not. please restart the service and check the mail flow.

Thanks

I did restart router engine..

also I find that I receive the error message return by server said


the e-mail account does not exist at the organization this messages was sent to......

could you please paste NDR here, if you would not mind and hide your confidential data..

The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address.

tried but still can't send from exchange 2003 to exchange 2010 or exchange 2010 to exchange 2003, also I found another issue, I can;t setup POP3 or IMAP in outlook 2010, only way to use in OWA

once more question, do I need to apply SSL cert to use pop3 or imap in exchange 2010?

final update...

I can send email from exchange 2003 to 2010 internally but can;t send email from 2010 to 2003

outlook can use exchange to connect but no imap and pop3, dont know shall I need SSL.

I figured it out. Looks like I didnt search hard enough. Under the properties for the SMTP Virtual Server on Exchange 2003 and then Under the Access tab and Authentication, I needed to have Integrated Windows Authentication checked.

by the way I am happy to split the point which give me a way to go..
