I am looking for some help folks. We are in a Outlook 2007/Exchange2010/Windows2008R2 environment.
When users open Outlook off the network, and occasionally on the network, they get the error
The name of the security certificate is invalid or does not match the name of the site error
The CAS hostname is HRECAS.XXX.ORG. The URL that is listed on the SSL certificate (issued by VeriSign) is WEB.XXX.ORG. WEB.XXX.ORG is what users use to get to OWA and such.
When I use testexchangeconnectivity.com, under certificate name validation I see an error that reads:
Host name autodiscover.xxx.org doesn't match any name found on the server certificate CN=web.xxx.org.
Does this mean somehow we have to add autodiscover.xxx.org on the certificate?
I tried to add AutoDiscoverExternalUri using http://support.microsoft.com/?kbid=940726 & http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/2d0c0f5f-e4ec-4f33-a37d-b94fd7a2319f on the CAS server.
Set-ClientAccessServer -identity HRECAS -AutodiscoverServiceExternalUri
https://autodiscover.xxx.org/Autodiscover/Autodiscover.xml
I get an error that says"a positional parameter cannot be found that accepts argument '-AutoDiscoverExternalUri'.
Can someone point to me what I am doing wrong with the command and whether I should be concerning myself with adding that line? By the way the InternalUrl information is already configured on the system. Also should I edit the certificate to add autodiscover.xxx.org?
Thank in advance for your support.
