I have a client that utilizes I Pads internally on their Windows domain network. They are attempting to re-task an I Pad to a different person. They did a factory reset (including all content) on the I Pad and set up the email account. They chose Exchange and it works as long as the user doesn't attempt to send an email with a picture attachment. The user can send pics as attachments through his PC w/Outlook with no issue. He can receive picture attachments on the I Pad with no issue. He can't send them. It gets stuck in the outbox with an explanation that the server rejected it. I have had them install the internal self-signed cert to no avail. The I Pad has not been updated to IOS 8. Tried removing and re-adding the account. Still doesn't work. They checked the settings against another I Pad that is working and everything appears to be the same. My forehead is bloody. Any help would be appreciated.
