Yes, change the Exchange version to 2007_SP1 from the menu &
reconnect.

At the beginning in the Exchange Version Field i had Autodetect.
I change it putting Exchange 2010Sp1 like in the log, but the error remain then same.

I'm continue to investigate.

You must be using an earlier version of Exchange, try changing it to 2007_SP1.

unfortunately it is not possible, i'm not the Exchange Admin, i'm only a user.
I have to wait " title="Sad" />

You misunderstand. Change the Exchange Version in OWAtray via the pull-down menu to 2007_SP1 and then re-connect.

I'm very sorry, i misunderstand as you wrote.

I already test al the option.

You definitely need Exchange 2007 however, with that setting, you are getting an error...

[09/03/2012 13:10:54] - Error:The request failed. Errore del server remoto: (504) Timeout gateway.

I don't know what that means exactly. Sorry.

Thanks for your help.
