I'm really confused. I've been using a succession of iPhones exclusively for about a decade now and never had the slightest issue with my email functionality. My needs are very simple. I use the standard, organic iPhone email program to monitor a single, solitary EarthLink email account. A MacBook Pro at home - again using the default OSX email program - also receives emails on this account and it is when I delete or transfer emails on this laptop that they are removed from the EarthLink server. I don't know that a person's email needs can get any simpler than that. Heretofore, deleting emails, or transferring them to folders, on my laptop had no effect on my ability to interact with the same email once it had been downloaded to my iPhone. Recently, however, I upgraded from the 5 to the 6S Plus. Now, half the time I go to view an email on my phone it says "message not downloaded from the server". As well, I just had an important email that I was composing on my iPhone vanish into the ether with the same message displayed. This was particularly frustrating insofar as this message had never been uploaded to any server - it had only ever existed on my phone. So just what in the hell is going on? Am I missing some simple setting? Does this have anything to do with all the goddamned "iCloud" ********* that Apple now seems to determined to shove down our throats at every opportunity? Or is there just some new basic level of incompetence now at work?
