I just set up my Exchange account on my Palm Pre Plus and it signed right in when I finished entering all the settings. I've received email, but it won't let me send any. When I send a message it says it's trying to send, but then says it's unable to sign in. I didn't get any kind of notification when I set up my account that there was a problem with the outgoing mail server...I have gotten this notification in the past so I just canceled the set up. I'm obviously signed in b/c I'm receiving emails. Tips?
