Built in email client... dreadful?

OK... So I have been using the surface for a day now and I have to say that the built in email client just seems dreadful!! Just switching between emails is painfully slow on my exchange account. It is even so slow that you can see it mark the next it as read if you delete the current item your looking at before it moves to the next it... Is anyone else seeing the same thing? I haven't used the built in client on my PC running Windows 8 too much because I use Exchange OWA... but man... I don't know that I could use the built in email client as a primary email interface.
