[CT] [ALL] What Are Your Directors Using for Emails? What about maintaining records?

I would love to know how other HOAs handle their email communication between each other, management, and homeowners. Directors come and go every year. Sometimes they still remain in the HOA and sometimes they sell and move away. If someone was a director in the past and using their own personal email account for HOA business are they obligated to turn over the emails? What’s the recourse if they refuse? We have nothing in our governing documents about doing board business by email which is done in between meetings. Thank you for your time.
