Hi Guys,

We have installed a wildcard certificate. Unfortunately users in the company are still getting
" the name on the security certificate is invalid or does not match the name of the site"
The server name being displayed in the warning is 'exchange.domain.local'

I Configured a DNS split zone as the domain is " .local " 
Followed instructions from this link:
http://www.msexchange.org/articles-tutorials/exchange-server-2010/mobility-client-access/using-pinpoint-dns-zones-exchange-2010.html

I have checked the settings of the webservices URL, Autodiscover URL and OAB URL and they all are pointing to  mail.domain.com

I am able to successfully ping mail.domain.com internaly

Not sure if something is broken on the IIS .

Any advice would be appreciate it.

Let me know if you need more info.

cheers R2

When you install a new cert on your exchange CAS server you need to make sure that you Enable the cert as well. Then removing the old cert as a cleanup measure.

Login to each one of your CAS servers and run the following command...
Get-ExchangeCertificate | ft

Enable-ExchangeCertificate -thumbprint xxxxxxxxxxxxxx -servcies "pop,imap,smtp,iis"

It will prompt you to change the new cert as the default press Y to accept.

Test it out and if it works then run
Remove-exchangecertificate -thumbprint xxxxxxxxxxxx

You have to enable the cert. Simply adding it to the server will not work.

Check autodiscoveruri by running get-clientaccessserver | fl

Set-ClientAccessServer -Identity "server" -AutoDiscoverServiceInternalUri https://mail.domain.com/autodiscover/autodiscover.xml

Also check if the third party certificate is configured on IIS default web site and Exchange backend website.

Hi Guys,

All the settings were correct.
It turned out that problem was with users outlook profile, Just recreating the profile fixed the issue.

thank you for your help.
