This solution worked perfectly for me. Thank you. Hadn't realized I kept the other account. IOS seems to fall back to that for sending.
When I start to delete my old account, I get a message that I interpret as all my old emails will be deleted. Can someone confirm that the old emails are kept?
Yes all old emails and saved items are kept because yahoo migrated everything over already to their platform. all good.
Thank you for your reply. This is the warning I receive when starting to delete the old cox account from my Mac Mail: "The account’s setup information, mailboxes, and all messages will be deleted permanently from your computer. Copies of messages on the mail server, if they exist, will not be affected." When I did this on my iPad, I lost the messages that were on my iPad but no longer on the server. I can't afford to lose all the emails that are in folders on my Mac, and (I suspect) no longer on the server. Can you confirm that your old messages are still available?
