A friend of mine has Exchange set up on their EVO 4G, works great... except when she roams or loses cell coverage. When she gets back within range of cell coverage it never resyncs with her Exchange. She has to delete the account and set it back up again in order for it to work again.
I looked at her settings, everything seemed fined. When we try to resync it doesn't give us any kind of errors, it just sits there showing all the emails up to the point that she went out of coverage. I updated her data profile, did a battery pull, still didn't work.
