OWA sneding problem with proxy

Hello,
We have a problem with external client behind a proxy : they can't send or reply email with Outlook Web Access ... "sending ... " stay a long time and they get an exchange error.

clients without proxy ( from my home for exemple ) can send, reply with no problem ...

I can't find solution. can anyone help me ?

thanks a lot

As Ian says, we need more details to understand your configuration. Maybe also a diagram showing the Astaro, the OWA server and the users that can and cannot connect to OWA.

Hello

As you can see in the attachement, the "only" difference is the proxy where the client is not working ( sending, reply ... but he can connect, read )

For the rules :
Maquerading : DNAT from external ASG adress to our exchange server with HTTPS service
Packet Filter : Anywhere to our exchange for https service.

I will post detailed information on Monday because i am not in my office...

Thanks
