I have my hotmail account setup in the normal email app for MIUI 1.5.20 on my Evo. If my inbox has more than 24 messages, and I delete any of the newest emails, I will receive a notification for new email, when in fact, it is the oldest emails back filling in because deleting the email created room. I could not find any settings to change how far back it should sync email. It would make sense that if the emails were limited by date instead of just plain number(volume), I wouldn't have this problem. Am I the only one?
