What do I do if the email I used to create my activision gets disabled because it was a school one

Question

What do I do if I don’t know my activision info and the email for it is disabled because it’s a school email

Answer 1

A phone number to call.

Answer 2

I'm a bit confused by your question, but Microsoft Customer support numbers are found here: Global Customer Service phone numbers.

If you no longer have access to the student account, then you can contact the school and see if they can reactivate it long enough to do what you need to do.
