Hello! We are in the process of migrating to Exchange 2010 from Exchange 2007. I am having issues getting Outlook to connect to our Exchange 2010 CAS Array.
Current System setup:
Windows Server Enterprise 2008 SP2
Exchange Enterprise 2007 SP2 (CCR Environment)
2 Mailbox Servers
2 CAS/HUB Servers (on the same box)
Windows Server Enterprise 2008 R2 SP1
Exchange Enterprise 2010 SP1 (DAG Environment)
Installed with Exchange 2010 SP1 DVD
Currently 1 Server with Mailbox/HUB/CAS rolls installed
Going to be reusing hardware above to create a 3 node DAG
Each server is on the same subnet.
We are using 2 CISCO 11500 load balancers that are configured with a virtual DNS name of email.
There is a certificate from our internal CA that has the load balancers Virtual name installed on the server.
We have single sign on setup and it works by going to either http://email/owa
on http or https (with no security warnings) We do not allow external connection to OWA so this is all internal.
I have also set a new CAS Array in Exchange 2010 and then attached it to each database. Under RpcClientAccessServer it gives the correct name.
Moving of mailboxes is not a problem and will stay connected to server until the transfer when everything changes and then says it will not connect.
When I open and manually configure outlook (2003, 2007 or 2010) and put “email” in there it does not want to verify. I then put the DAG name in there and it autocorrects to email BUT will not connect because it says exchange is down. If I put in JUST the server name and have it connect it works just fine. So it is something with the CAS Array that is stopping the process.
Any help would be greatly appreciated!
