Is there any way, either natively or via 3rd party to have the system periodically sync other email folders I have setup, such as my favorites? As you know, the standard email only updates the inbox in the background.

THis really sucks as I heavily rely on server side rules on our exchange server to sort my email nicely into folders but I always have to wait for the very slow sync to update them manually when I want to check.

My old Chatteremail handled this beautifully.
