How to copy/export emails from old iPhone I use iPhone’s Mail app to get my emails. I got a new iPhone and found emails are not copied from the old iPhone. It seems the logic is to download emails from the email servers again. However, one of the email service has shut down and no service anymore. How can I retrieve/export emails from this email account? I have catched emails in my old iPhone.
If at least one of the Mail Accounts available on both phones you can

create a mail folder in this account
copy all mails from the shutdown account into this folder (on the old phone)
wait a while to have the phone sync the mail folder back to the Server
access the Mail folder from your new phone
