Exchange No Mail from 2010 -> 2003 / 2003 -> 2010 is okay!

[oxide54]

btw the same post is here No Mail from 2010 -> 2003 / 2003 -> 2010 is okay!

 

Domain a : admin domain

Domain b : curriculum domain

 

I cannot send email from a 2010 mailbox to a 2003 mailbox, it queues on the hub transport server. when i check the queue i get a "451 4.4.4 DBS Query Failed. The error was: SMTPSEND.DNS.NonExistentDomain; nonexistent domain"

 

what domain can it not find?

 

OWA is working and i can send from a 2003 mailbox to a 2010 mailbox just not vice versa. I have only moved my mailbox for testing purposes so I can get this working before migrating any other mailboxes to 2010.

 

OWA also correctly redirect user to 2003/2010 depending on where mailbox is hosted.
