Autodiscover fails (Exchange 2010)

Getting two errors with Autodiscover when connecting using Outlook 2010. The errors seem to be at random as far as which one occurs, so I am quite sure they are related. But how, I just don't know. It happens with all of our accounts. Manually configuring the accounts in Outlook works just fine, as does OWA, so it seems to be just an issue with Autodiscover. The Exchange Remote Connectivity Analyzer shows that Autodiscover works fine, but clearly something is wrong. Our setup is listed below.

Error #1 - " The name cannot be resolved. The name cannot be matched to a name in the address list."

Error #2 - " An encrypted connection is not available"

Our Exchange Configuration
2 Exchange 2010 servers. Both have CAS\HUB\Mailbox roles installed 1 DAG group 2 DCs that do not have Exchange installed All servers running Server 2008 R2 64-bit New deployment, so we have never had previous Exchange versions installed.

Thanks for taking a look, and I look forward to the helpful suggestions.

So you have two servers with all roles installed and in a DAG...
Do you have a CAS Array configured? What IP address does your CAS array point to? Autodiscover point to? Are you load balancing your CAS servers? With a multi-role, two node DAG, only hardware loadbalancers are supported

Tim,
Thanks for the reply. You may have pinpointed our problem. We don't have any CAS Array configured. We're just using DNS round-robin. Could that be our issue?

Tim,

Is there anyway to test that this is the issue before we go to the trouble of purchasing a hardware load balancer? I was thinking of changing the autodiscover A record to point directly to one of the servers.

That is correct, you can point all of your autodiscover and OWA DNS entries to one of the CAS servers to test. make sure that the autodiscover, owa, and any other names defined in the CAS URLs (OAB, EWS, ECP, etc) are part of the certificate that is enabled for IIS and also that it is trusted. Recommendation is using a public cert.

Already have a UCC cert installed and working. OWA works great with it, so I'll go ahead and point the entries to the one IP and see where we get from there. Thanks for your help, and I'll update once the DNS propogates.

Hi,

1, Confirm the Mailbox Database is associated with the Default Offline Address Book.

2, Confirm the Authenticated users have the permission to read and download the Default Global Address List.

3, Cofirm the showInAddressBook attribute.

Thanks

Allen
