Google Apps GMail for students

[josephathon]

I am looking at setting up Google apps for student use and would like them to have Gmail addresses rather than exchange mailboxes. I have setup Google apps and our domain has been verified. Ideally I would like staff to continue using exchange mailboxes and students to use Gmail. I have set up a sub domain in google apps student.mydomain .co.uk and this works when I email from outside the network to an email address outside of our local domain. I cannot send email from inside the domain to a student.mydomain.co.uk email address. And the studentmydomain.co.uk address cannot email an internal address at mydomain.co.uk

 

Is it possible to set it up like this and if so how do I get internal email addresses to send mail to the student.mydomain.co.uk gmail addresses and vice versa?

 

Any help would be greatly received.

 

Thanks

Jonathan

Have you set MX records?

MX records have been set at 1&1 for the sub domain. When I send to mydomain.co.uk from outside the school I get sender address rejected You're not in mydomain.co.uk. But I can send from an external address to another external address. I think it is something to do with our exchange server.
