A few email questions

[biggggant]

I use Exchange Active Sync for my work emails and I just noticed that the Hero syncs all my folders. Is there a way to choose folders? Also is there a schedule that the phone uses for active sync. Because I have noticed that in the middle of the night my phone will not get any emails and then usually right around the time I wake up I have all the emails from the middle of the night waiting to be read. I get emails all the time from 12:00 7:00am but when I wake up in the middle of the there are no emails on the phone.
