Exchange 2007 - Having Multiple CAS

Hi,

I have currently got the following setup:

1 x Exchange Server that is running all of the roles (90 Mailboxes, 500GB Information Stores (4 Stores)

Exchange Version: Exchange 2007 SP1 (Build 240.6)

We have now got over 40 ActiveSync clients so I am looking to add an additional CAS that is just to handle OWA and ActiveSync requests.

My question is this

How do I add an additional CAS and how do I configure it to only handle OWA and ActiveSync requests but not MAPI requests from Outlook Clients. Basically I don't want the End User Machines to talk to this additional CAS.

Thanks very much

Paul

your cas is accessible by a url so as long as webmail,domain,com for example is pointing to serverA serverB will not be used,

for the second part of the question you will need to define different urls for owa and activesync for this. Say webmail.domain.com pointing to serverA and activesync.domain.com to serverB

in exchange 2007 mapi clients will connect directly to the mailbox server and not to the cas server so you basically have nothing to do for this.

Just change the DNS entry of your owa/activesync to point to the new cas

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

On another note, if you have multiple CAS how do you know which ones are used?

ie if I install a new one, how do I stop it from being used by clients until I am ready?

Also if I only want it used for activesync clients and not owa is that possible? basically i want a specific CAS just for activesync clients.
