I am having a headache with my Exchange 2010 Server. I have some smartphones that will connect and be able to access email remotely and others that won't.
It started with a Motorola Droid Turbo I had. It wouldn't connect and I thought it was the phone. I replaced it with a Lumio 735 and it has the same problem. It acts like everything is fine, then it will try to sync and it comes back and says "Not up to date." I have tried with my personal phone, a Galaxy S5. It goes though the setup fine and completes. Then when I go into my app there are no messages, and if I try to send something it fails. I know the phone is talking to the Exchange server because if I type in my password incorrectly it will say I have the wrong credentials.
Meanwhile, I have an employee with an iPhone 4S who has no problems, and other with smaller Samsung smartphones that work fine as well. I don't understand how some phones work and others don't. What am I missing?
BTW, we are using SSL.
