Thanks Yosh,--------------------------------------------------------------------------------- YOSHIKA04 ------------------------------------------------------------------------------ Friday, March 25, 2011 5:23 AM Reply | Quote Answers 0 Sign in to vote Hello, Firstly, I would like to ask whether the symptom occurs on an Internal Outlook client or an external Outlook client. If it occurs on an External Outlook client, I think we are using Outlook Anywhere and we have to add the “mail.abc-company.com” to the domain names in the certificate. If the error occurs on Internal Outlook, we can workaround this issue by turning off “Outlook Anywhere” by: 1. On a problematic Client, open Outlook. 2. Click Tools >> Account settings. 3. Double click the profile name and click More Settings. 4. On the Connection tab, unche

proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target http://markgossa.blogspot.com/2015/10/outlook-2013-there-is-problem-with-the-proxy-servers-security-certificate.html site server.domain.com. Outlook is unable to connect to the proxy server (Error http://serverfault.com/questions/693570/the-name-of-the-security-certificate-is-invalid-or-does-not-match-the-name-of-th Code 10) The name on the security certificate is invalid or does not match the name of the site The cause of these errors is that Outlook is connecting using Outlook Anywhere although it is able to contact Exchange, it is using a name that is not on the proxy server certificate. To resolve the issue, there are two options. Either you need to create a new certificate request and add the name to the certificate (see here for instructions) or you need to configure Exchange not to autoconfigure Outlook with this name and specify a different name that is on the certificate. This autoconfiguration is known as autodiscover. More on that the proxy server in another post. In this post, we'll look at how to configure Exchange Outlook Anywhere so that this issue no longer occurs. 1) Confirm current Outlook Anywhere hostnames We need to confirm that the Outlook Anywhere hostname includes the hostname in the error, in our case litex01.litwareinc.com. To do this run the below command: Get-OutlookAnywhere | fl ExternalHostname,InternalHostname 2) Create DNS records We need to choose a name that is included on the certificate that is used by the CAS servers and/or reverse proxies. In our case, we will use the same name, mail.litwareinc.com, in internal and external DNS as we are using split brain DNS. You can use different names as long as both are included on your certificate. Using a single name is simpler for troubleshooting and means that less names are required on the certificate which can reduce your costs in some cases. The internal A recordneeds to resolve to the internal IP of the CAS server or load balancer virtual IP if you are load balancing multiple CAS servers. The external A recordneeds to resolve to

Today I bought a trusted SSL certificate (wilcard) and installed on the server. The certificate is issued to *.example.no and gives no security exceptions when I access the web interface at https://mail.example.no/owa from the web browser. Now, when I open Outlook I get this certificate validation error. I've tried all the standard solutions provided, which mostly involved setting the external url as the internal url. Internal FQDN: mx.example.local External FQDN: mail.example.no Error message: There is a problem with the proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target site mx.example.local. Outlook is unable to connect to the proxy server.
