I am setting up office 365 so that we can share documents with everyone in our organization. We already host an exchange server in the cloud. I would like to setup our current domain with office 365.
During the setup process they ask to add a test MX record for verification, but I already have and MX record pointing to an exchange server. I don't want this "test" to affect the current MX record.
Am I okay in setting up the test? Once the domain is attached, will there be two exchanges?
