My iPhone 6s Plus has been deleting emails on its own lately. It did this before then just randomly stopped and now it's started again. When I go to my Mac and check my mail, all of the mails are in my Inbox. But they're still not there in my mail on phone. It's only doing it with one account, my school email through Outlook. My Gmail emails all stay. What could be causing this?
