Seems like there happened a misscommunication, there are 3 ppl in the org that could be perceived CTO. 1. You 2. The old CTO that wants to keep their inbox 3. The guy hired for the job. You need to talk to founder to let them decide. Another thing is - if you hire new people and they didnt finish the onboarding yet, things will be breaking, thats the circle of life. If the new guy is expected to know these things or he repeats the same mistakes - then he is not meeting expectations and should be let go. I think you three need to have a candid conversation about the expectations, maybe include a founder who can be a tie breaker. Definitiely, such a mess in so small org increases the potential of failure drastically.
