Exchange 2010 Split Delivery same domain
Posted on 2010-08-27
I have one Exchange 2010 with one domain MyDomain.EDU now all of our students email accounts in Google App, however we would like to move all the staff (employees) to Exchange 2010 and leave the students in Google Apps.
my DNS MX pointing to Google Apps. And I setup Google Apps to deliver any emails to unknown accounts back to Exchange.
IN Exchange 2010 the Accepted Domains is setup to Internal Domain.
I setup an internet Send connector. I tried the Smart Host which I do not have one and the DNS MX record.
I am able to receive and send emails to Exchange, from outside sources for example email@example.com I can also reply. Also Internal email work from one exchange account to the other.
HOWEVER: If I send an email from Exchange mailbox for example firstname.lastname@example.org to a Google app account which using the same domain let say email@example.com the message will not deliver.
I followed several articles to try to setup exchange to send all messages to the internet regardless in they are internal or external and could not find a solution for this issue.
