Iphone 6s, disappearing emails
Hello
I have a problem with emails on business 6s.
Received emails disappear from the inbox after about two weeks. They are not moved to the archive or the trash, or to another folder. They just disappear. I also receive them on the computer in Microsoft Outlook, they stay there, everything is ok. It's all about e-mails on the phone. Mails normally arrive, I send normally. In the settings I have set that e-mails are never moved to the trash and archive. Where to find the reason
