When i create my account i was using a corporative mail, because it's primarily to share notes betwen my coworkers.
But the company (who have a google account on the time), has been changed the mail provider, and now we are using Microsoft accounts.
I still can receive mails from the old mail account, but that it's not a google account anymore.
Here begin my problem, when i try to change my mail account it's asked to login in google account, but i don't have that account anymore. =P
How can i change my mail address without needing to verify the account in google?
