I have an iPhone 5 and 3rd generation iPad, so I've used email through apple products and have never had a problem. All my contacts, email and calendar appointments show on both devices easily, never a problem. For some reason my email won't delete through the iMac email client at all. It always shows back up, and my hotmail email account, the calendar events don't show up on my calendar, and my work email which events do show up, says in the calendar that that email address isn't valid, even though it does display my appointments. Being a first time iMac user, and it obviously being a bit different from the mobile iOS, I really have no clue where to start. Thanks in advance for any direction.
