Exchange 2013 removes sub domain when replying to emails

Hi,

We started a pilot with Google Apps for Education and currently have an internal Exchange 2013 server. Our teachers have an Exchange mailbox (myschool.ca) while the students are using a Google Apps for Education email account (gafe.myschool.ca).

When a student emails the teacher, everything is fine but when the teacher attempts to reply to the email, the mail client (iOS mail, Outlook 2013) removes the "gafe" portion of the address and assumes the recipient is an internal myschool.ca contact. The teacher obviously receives an NDR.

Any ideas?

Adding the internal MX record did the trick. Thanks Guy!
