Help Problems in modifying appointmens w/ Exchange

[yougenio]

Hello, I've a problem in updating appointments with exchange.

I use outlook on my pc, anc calendar on iphone and ipad. All is syncronized. I can see all agenda updated from anywhere.
Also, If I set an appointment on my pc, I can update it from iphone or ipad. When I set an appointment on iphone/ipad I can update it on my pc. All appointments can be updated from anywhere.

Yesterday I bought a Samsung GalaxyS with Android. I setup my exchange account and all my android agenda was perfectly displayed on galaxy.
When I set an appointment on my android, it is visible in a few minutes on Pc/iphone and ipad. And when I set it on pc/iphone/ipad it is visible in a few minutes on Android as well

The problem:
- When I set an appointment on my android I can cancel/update it from pc/iphone/Ipad (good!)
- When I set an appointment on my pc/iphone/ipad I see it on Android but I'm not able to cancel/update it

Can you please help me whith this issue?
Thank yoy
