Interorganization between Exchange 2003 and Exchange 5.5 |
|

Hi folks,
This is driving me up the wall and I cannot see what I have done wrong! I've tried following Microsoft's guide to not much use.
We have a NT4 domain with exchange 5.5 and a new 2003 active directory domain with Exchange 2003. These need to operate together while we slowly migrate users.
New users in the 2003 domain have two email addresses - @company.com and @temp.company.com. Exchange 5.5 IMC is set to forward any email sent to @temp.company.com to the 2003 Exchange server. Each migrated user has a contact created in Exchange 5.5 with the @temp.company.com as it's address and the exchange 5.5 mailbox is set to forward to this address - this works fine and I can email from Exchange 5.5 to Exchange 2003.
I have used ADC to create contacts in the 2003 domain with smtp email address @company.com - these users still have active mailboxes in the 5.5 setup with the same smtp addreses.
When I try and send an email from 2003 to one of these contacts exchange generates an NDR (although this is not delivered to the user - can be viewed via message tracker). Its as if it is trying to send the email locally within the 2003 Exchange server and realises the mailbox doesn't exist and bounces the message. I've setup an SMTP connector to point back to the Exchange 5.5 IMC but it will not route emails to @company.com over this connector. I've tried specifying @company.com as the address space to no use.
What have I done wrong - this looks correct going on Microsofts documentation although it is not very detailed.
Thanks for your help
Rob
