Had old domain a friend had been using an email on for 20 yrs. I stopped paying Google for email service, thinking no one was using it. Spent days to 1) Get her email address back, 2) Get all the old emails and 3) Get them from recovered/renamed account to the newly created email acct.
Since I have an app in the email space, I appreciate more than you know the work and probably how hard that was to deal with 😅
