I have a new One X+ and am new to HTC devices. For the most part, I am happy, but am having a nagging problem with the mail app:

Often when I go to open an email (from an Exchange server) that has been pushed to the phone there is a delay of 30 seconds while the circle at the top of the screen spins. Sometimes there is no delay at all (teh behavior can even be different for all text emails received at almost exactly the same time). I cannot tell why this is, but it can be quite annoying. I have also tried Touchdown, which does not exhibit this behavior.

Any ideas?
