offered by Exchange 2007. These web services (OAB, Unified Messaging, OOF, and Availability) provide a good portion of the new functionality available to Outlook 2007. For more details about the Outlook 2007 features

that light up based on the Exchange server version, please see Outlook 2007 feature matrix based on Exchange Server version. For domain-joined clients, Outlook is able to find the Autodiscover service using a service connection point (SCP). The SCP is an Active Directory entry specific to each client access server. When Outlook 2007 is able to securely connect to the domain and read this entry from the name on the security certificate is invalid or does not match the name of the site outlook 2010 Active Directory, it can connect directly to this URL. Once connected to the Autodiscover end-point, the Autodiscover service provides the client with the URLs of the other exchange web services. For non-domain-joined clients or clients that are not able to directly access the domain, Outlook is hard-coded to find the Autodiscover end-point by looking up either https://company.com/Autodiscover/Autodiscover.xml or https://Autodiscover.company.com/Autodiscover/Autodiscover.xml (where company.com is the portion of the user's SMTP e-mail address following the @ sign). This means that to service clients in this scenario we must provide connectivity to one of these URLs. On the surface this should not be hard; but this connection is made over SSL and requires a valid certificate. SSL and Certificates The communication to the Autodiscover end-point and subsequent communications to the services all occur over SSL. This requires that we have valid certificates (signed by a trusted CA, with a Subject Name matching the URL the user is connecting to, and not expired) for the Autodiscover connection point and the services URLs. By default the services URLs are all variations of https://serversname. When you install a Client Access server, Exchange Setup creates a self-signed certificate that meets validity tests for domain joined c

This problem will occur if the following conditions are true: the internal DNS namespace does not match autodiscover certificate the external DNS namespace (eg domain.local for internal and domain.com.au for external) a third party SSL certificate matching the external namespace has been applied to the IIS instance on the Client Access Server (eg cas.domain.com.au) The certificate mismatch occurs because the Autodiscover Service and/or Availability Service use the FQDN of the Exchange 2007 host in autodiscover certificate error their URL (eg https://server.domain.local/AutoDiscover/AutoDiscover.xml) but the IIS instance has an SSL certificate that does not match that name. To resolve this issue you can change the URL of the Autodiscover and Availablity services to match the name on the certificate, which you can do with the following shell commands. [PS] C:\>Set-ClientAccessServer -Identity cas.domain.local -AutoDiscoverServiceInternalUri https://cas.domain.com.au/Autodiscover/Autodiscover.xml [PS] C:\>Set-WebServicesVirtualDirectory -Identity "EWS (Default Web Site)" -InternalUrl https://cas.domain.com.au/EWS/Exchange.asmx -ExternalUrl https://cas.domain.com.au/EWS/Exchange.asmx As long as your internal clients are resolving the external name cas.domain.com.au directly to your Client Access Server this should resolve the certificate mismatch error.

In this article, we will take a deep dive into the Autodiscover feature in Exchange 2007/2010. If you would like to read the next part in this article series please go to Exchange Autodiscover (Part 2). Introduction When Microsoft released Exchange Server 2007, one of the new features it included was Autodiscover. Autodiscover allows you to automatically configure Outlook 2007 clients, but, there is a lot more behind the Autodiscover functionality. When you have issues with the Out-of-Office or Free/Busy information in Outlook 2007 in combination with Exchange Server 2007 (or Outlook 2010 and Exchange Server 2010) it is likely that it is caused by a misconfiguration in the Autodiscover configuration. To make things more complex, the SSL certificates are involved here as well. Note:The Autodiscover process for Exchange 2007 and Outlook 2007 is practically the same as for Exchange 2010 and Outlook 2010. In this article I will use Exchange 2010 and Outlook 2010. Autodiscover information is stored in a so called SCP or Service Connection Point. You can view this SCP using Active Directory S
