Run down of our environment
google apps serves as the mail server for our own domain
Some people use the native gmail apps to send and receive emails, but a while ago some people asked to get office 365.
As a test we used 3 accounts that we successfully migrated to office 365 so they use the outlook app as a mail client.
PROBLEM: Those accounts receive and send mail just fine to anyone EXCEPT people inside the organization which never get the incoming email.
From what I was able to gather, the problem seems to be at the SMTP, since the config seems to be the standard smtp.office365.com (the default config for office365) but I guess that the SMTP thinks that it is in control of the domain (Email wise anyway).
QUESTIONS: Is it possible to change the default SMTP on Office365/Outlook?
If so, How?
What should the SPF record be with this setup?
