Exchange server send/receive

[dukhead]

All of a sudden when ever i compose an email on my 700wx, it doesnt send immediately. I am using exchange server. I made sure that "send items immediately" was checked. I dont know whats going on. I have to wait for it to sync for it to send. And on my old 6600, i could just hit the send/receive button, well thats greyed out can someone help please. Because sprint and my IT departments general solution to every problem is a hard-reset.
