I am the administrator on a G-Suite for Education domain.
We have a domain name set up (say ourschool.org) and students use firstname.lastname@example.org to log in to their Google accounts.
Our MX records however are set up to facilitate an O365 account on the same domain. This O365 account is used by staff for e-mails and for students to get access to Microsoft Office for free at home. We don't want this to change.
Obviously we knew this when we set up the Google account - we had no requirement for mail use on the Google accounts.
However, we're now missing a few small features which the curriculum IT staff would like to access - feedback notifications (through e-mail), etc.
We've purchased another domain and set up the relevant Google MX records. We've also added this as an alias in our Google account. Let's call it our.school.
Is there any way to force all e-mails (especially the feedback notification e-mails etc) to use this aliased domain our.school whilst still allowing staff/students to login using their existing e-mail addresses on the original ourschool.org domain?
