My son has a @schools.vic.edu.au email address from their school. I was trying to register for Lenovo education store for this deal but the account registration email was never received. Then I tried sending an email to his email address from my work email which also was not received. That makes me think that my son's google account is not allowed to send/receive email.
I have seen that he has sent an email to his class fellow and a lot of emails from teachers. Looks like all messages in Goggle classroom are also available in Gmail but no outsider emails.
Does anyone have more information on this or experienced this? Does it mean I cannot use his address for the education stores?
