It may take you to wait a week after creating a new refresh token

Create a new google oauth refresh token
Check after some days (general behaviour is after a week), the refresh token isn't valid, and calls requiring it fails too.

Access token are valid for short time, but the same is not true for refresh tokens, it should be able to send the mail.
