Seems Android's claim of working with MS Exchange is slightly exagerated. I've reported a bug that they have replicated and said they'd look into. HTC/Android is fabulous! My previous phones with MSMobile never addressed and bug issues. Anyway, careful creating from the phone full day events. They can show up on different days on Exchange servers. Also, if you have full day recurring events, they can get screwed up too, particularly if you try to edit them from the phone.
