Hi Sean McHugh. Did you solve this issue?

I have a similar challenge I believe. Customer wants to keep using Google Apps email for now but is using O365 SharePoint. How do I get emails generated in O365 to send to the Google system?

I hope to hear from you?

It was pretty simple ... i was missing one piece of information about O365 connectors to finally complete this.

a.) setup the mail domain on your O365 tenant using TXT record validation

b.) setup an O365 connector to route mail to that domain via the published Google MX.

c.) on the Accepted Domains tab of the Mail Flow settings, change the domain from Authoritative to Internal Relay

I think I've done the correct configuration but the validation step always fails. Is this normal? Thanks.

as long as it's not "authoritative" it should work without issues. Internal relay also tries to deliver locally first. Using Criteria Based Routing is the alternative to the method you just described

  Another question, should the Exchange inbox be enabled or disabled?
  Thank you.
