Mailo Notifications For New Mail In Subfolders iPhone

We are rolling out Office 365 Microsofts new cloud solution for Exchange and have been running iPhones, iPads and Windows mobiles. Amazingly good response back from useres on the Apple offers which is great. One issue we have is that some users have rules set up on their Exchange inbox where emails are diverted to certain folders accoring to their content or the sender. The iPhone doesnt seem to provide any notification of new mail in these sub folders. Has anyone come across this or even better have a solution or how to handle this?
Thanks loads
