OOF needs to be enabled on exchange.

Speak to hosting provider to enable this.

I am the hosting provider, i am in charge of exchange servers.
The problemhas been solved by himself.
After a day OOF is vaialable for everyone without any action.
I assume it was just the time for the other server to enable their features.

Thanks for help.
