I have two email accounts set up - one Exchange and one IMAP. For both accounts, I have non-peak hours set from 10 pm to 8 am and have the delivery set to manual. However, sometimes the email notification (it's different from other notificatons) will go off in the middle of the night and the email icon in the status bar. Anyone else had this problem? I'm wondering if there is another setting somewhere else in the phone that's causing this to happen. Thanks for your help.
