The name of the security certificate is invalid or does not match the name of the site

After starting MS Outlook 2007 or 2010 and connecting to MS Exchange 2007 or 2010 server (on a local network) you get warning "The name of the security certificate is invalid or does not match the name of the site"

This happens because of certificate names mismatch. For more information read Microsoft article KB-940726

To fix the problem:

Open MS Exchange Management Shell.

To find our information about your Autodiscovery server run:
Get-AutodiscoverVirtualDirectory | FL

To fix the certificate error run following 4 commands replacing:
<server_name> - Your Exchange Client Access (Autodiscovery) server name.
<mail.yourdomain.com> - Your exchange server FQDN (valid for your trusted certificate).

Set-ClientAccessServer -Identity <server_name> -AutodiscoverServiceInternalUri https://<mail.yourdomain.com>/autodiscover/autodiscover.xml

Set-WebServicesVirtualDirectory -Identity "
<server_name>\EWS (Default Web Site)" -InternalUrl https://<mail.yourdomain.com>/ews/exchange.asmx

Set-OABVirtualDirectory -Identity "
<server_name>\oab (Default Web Site)" -InternalUrl https://<mail.yourdomain.com>/oab

This 4th command is not required on Exchange 2010
Set-UMVirtualDirectory -Identity "
<server_name>\unifiedmessaging (Default Web Site)" -InternalUrl https://<mail.yourdomain.com>/unifiedmessaging/service.asmx
