I have a manager that just got an iPhone 6 and we use Exchange Online. All of his email folders are usually in sync with his iPhone but since going to the 6, he cannot see all of them. I've refreshed his exchange box, credentials and even removed and re-added his exchange account. It will only show a handful of his folders and that's all.
OWA shows all folders and for sure, his Desktop OUTLOOK is fine.
Any suggestions?
