Hi,
we want to migrate our Exchange 2003 to Exchange 2007 on two active directory sites but we have only one OWA2007 in dmz.

Is it possible to access with one public url to different Exchange2007 Server with roles Mailbox Servers + Access Client Serveur ?

actually, this is not ok for exchange2007 but it's works fine with Exchange 2003.

A CAS is required in each AD site in which you plan to deploy an Exchange 2007 Mailbox server.

It's also against security best practices to deploy a CAS in the DMZ. You should instead deploy the CAS on the internal network and publish it using a reverse proxy such as ISA Server.

I have already a CAS in each AD site.
I have already a CAS in the DMZ
if the 2 cas in ad site have the same external url : that doesn't work

a fourth CAS is necessary to publish it in ISA Server ?

the external url of my 2 CAS Server in AD SITE must have wich external url ?

Thanks for yours responses and excuse me for my bad english.

I have installed an isa server 2006 in the dmz.
I have my 2 exchange 2007 Servers in my 2 active directory sites wich have roles : mailbox, hub, cas
i have published the first exchange 2007 in the isa 2006
this works fine for my first exchange but not for my second exchange.

Is it necessary to install a third Exchange 2007 with only CAS and publish it instead of my first exchange ?

An additional CAS is not required in this scenario. I can highly recommend you give the below section in the E2K7 documentation a read, as it should answer all your questions as well as give a overall impression of the behaviour of CAS.
