Need to get into previous iCloud email
I recently made a new Apple ID and didn't know it would delete my existing iCloud email off my phone. I have tried to add that email account to my outlook but it wont let me. It says I need to have an app specific password now but it still isn't really working. I have important emails on that email account that I still need access to. If I had known that it wouldve deleted the email account after making the new ID i wouldve waited or saved the eamils beforehand. Is there a way to either regain access to the emails or forward them to a different email account?
