It looks like you may have your question answered here (comment 8):

http://blogs.msexchange.org/walther/2010/06/09/exchange-2010-sp1-change-to-how-static-ports-are-assigned-on-a-cas-server/

but for everyone else, Exchange 2010 doesn’t need this port/service. Pick any number you want and then delete it once the template is complete.

Hi,

I am trying to setup Exchange 2010 SP1 with our f5 config. During the configuration i am asked to specify 3 ports:
1. MAPI
2. Address Book
3. Referral Service
However, we are not able to find any information regarding the Referral Service in Exchange SP1. The RTM has references to it. When we try to configure our f5 with the same port as the Address Book for the Referral Service we get an error stating we cannot use the same port number.

Do you have any insight into this issue?

Thank you.

The CAS array only load balances Mapi traffic you would create a load balance for your AS name space as well…. Since the CAS servers handle all traffic now this could be the same vip or different. I typically like to setup one name space for mapi and one for owa/as/etc…

Is the CAS array going to load balance only the MAPI conection or it will also load balance Active Sync, AutoDiscover and Availability Services ?

To recap you created an rpc arry with NLB and how many CAS servers do you have in the NLB? Have you validate the services are running on the CAS server? Did you perform port scoping or just default? have you dont a packet sniff to see if the client it making it to the CAS array?

I followed the steps mentioned in this article but my Outlook client is not able to connect to the server. I’m getting an error:

Cannot open your default email folders. You must connect to Microsoft Exchange with you current profile before you can synchronize your folders with you Outlook Data File.

Yes, you can have the CAS and Hub server role on a single server and use NLB. Just note the internal connectors cannot be apart of the nlb for the hub transport servers

A quick question. Can I install Exchange 2010 Client Access and Hub Transport on the same server with NLB? These are the steps I’m going to follow, please correct me if I’m wrong:

- Configure NLB on 2 Servers running Windows 2008 x64.
- Install Client Access and Hub Transport Role on those server.
- Associating the Array with databases.

All Set?
