How can I get my old email onto my new iPhone?

Episode 1120 (2:28:07)

Evan from San Diego, CA
Apple iPhone 6 and 6 Plus

Evan got an iPhone 6 and set up his Outlook account. However, the folders that he has set up appeared without the emails that were inside of them. Leo says that Outlook uses Exchange and it should get duplicated, but it could be stuck. He should try removing it and adding it again. It may also be that the older emails won't show up since the OS doesn't want to overwhelm the phone by downloading thousands of emails. There may be a setting in email that would allow him go to back and get the older email.
