Help Email subfolder and calendar notifications

[mpeeng]

I have the HTC desire connected to my Microsoft exchange account. I have several sub folders that emails are automatically delivered to. I can see these sub folders on the HTC, but it doesn't notify me when a new mail goes to any folder but the inbox. Is there a way I can change this so that I'm notified whenever new mail goes to any of my folders? Also the way my calender is set up in exchange is other people have write access to my calendar (so my superiors for example can add important events to my calendar). Is there any way for the HTC to notify me when a new entry has been posted on my calendar?

Thanks,
