What type of Certificate is needed for CAS 2007 server   
We are going to be replacing our OWA 2003 server with a CAS 2007 server in 
preparation for an Exchange 2007 migration. Today, the OWA server handles 
Outlook Mobile Access, Outlook Web Access, and RPC/HTTPS redirects for our 
clients. In the new environment, the CAS server will handle the same 
requests. We are not deploying any unified messaging at this point.

What type of certificate is required on the CAS server? I am being told a UC 
certificate is required, however I am reading that a simple SSL certificate 
will perform all of the functions.

Please help!

Steve

If you want to support autodiscovery for external Outlook ANywhere
clients, for ease of use and management a UCC cert makes sense.

owa.yourdomain.com
autodiscover.yoursmtpdomain.com

RE: What type of Certificate is needed for CAS 2007 server   
Hello Steven,

Thank you for your post. My name is Robbin Meng, and it is my pleasure to 
work with you on this issue! 

Please allow me to confirm that my understandings are correct. As I 
understand it, the issue is:

You would like to add a new Exchange server 2007 as the CAS server role to 
replace the previous Exchange 2003 server which ever handles Outlook Mobile 
Access, Outlook Web Access, and RPC/HTTPS redirects for clients.

If I have misunderstood your concerns please feel free to let me know.

What do mean by "UC certificate is required"? As far as I know, there isn't 
any special certificate needed for you. 

Actually, if you would like to use Autodiscovery, you may transfer Exchange 
Server 2003 Certificate to Exchange Server 2007 Autodiscover Server

In this scenario you have a certificate you are already using on an 
Exchange Server 2003 server and want to implement it on your new Client 
Access Server. This scenario would only be applicable in an environment 
where your presence on the Internet might be a single namespace such as 
domain.com and the certificate you have is issued to domain.com. This would 
require https://domain.com/Autodiscover/Autodiscover.xml to be accessible 
from the Internet.

1.	On the server where Microsoft Exchange Server 2003 is installed use 
Certificate Manager to export the certificate as a .pfx file from the 
server.
2.	Copy the .pfx file to the new Microsoft Exchange Server 2007 Client 
Access Server.
3.	Import the pfx certificate file using the Import-ExchangeCertificate 
cmdlet as in previous scenario examples.
4.	To enable the certificate for use on the server use the 
Enable-ExchangeCertificate cmdlet as in previous scenario examples. 

Hope this helps. Also, if you have any questions or concerns, please do not 
hesitate to let me know. 

Thank you for your time and cooperation!


Best regards,

Robbin Meng(MSFT)

He means a UCC certificate. One that uses a Subject Alternative Name.
