Cannot make transition to Google email on my Outlook on a Surface.

[wireless]

We have successfully transitioned from Telus to Google email service on our Outlook on our desktop. But have not been successful in the transition on our Outlook on our Surface. We have made all the changes but then when we try to "test the settings" the login box just pops back up. It does not provide any errors or codes....

Any ideas what could be wrong?

Yes, we have closed Outlook, and rebooted.
