I didn’t sign in for a long time and the account is now closed. How can I retrieve the email from it?
you cannot retrieve your email account if you have not logged in since 6 months or more.
Cant be done if account is deactivated.
It's common on all email provider's Terms of Service that after a certain period of account activity,a user's account shall be terminated and all the data related to it will be deleted permanently and the user id will be made to public.
Sorry m8, but it looks like you won't be able to retrieve any mail from your account once it has been deactivated.
