Can I recover sent emails from an iPhone 4s in my new iPhone 6
I upgraded to a new iPhone 6 (from a 4s) yesterday and everything has transferred over pretty well. There were some initial problems with my mail set-ups but I have re-entered passwords and can receive mail. The question I have is whether the mail messages I sent using the iPhone 4s can be viewed in the new iPhone. All of the messages that were in my inboxes transferred, but the Sent Items folder only contains messages sent using the new iPhone. Am I able to retrieve them or are they lost forever?
iPhone 6, iOS 8.1.2
