Both my husband & I have iPhones (mine 5s, his 4s) & we have our yahoo business email set up on them both. We also have this email set up in Outlook 2011 on our iMac, but whenever  I move (file) an email in Outlook, it completely deletes it from our phones. I don't know how to fix this, & it's driving us both crazy! Can anyone help, PLEASE?
