Security warning when you start Outlook 2007 and then connect to a mailbox that is hosted on a server that is running Exchange Server 2007 or Exchange Server 2010: "The name of the security certificate is invalid or does not match the name of the site

If you run SBS Server 2008 and you have a third party SSL Certificate for your Exchange Services you can find this error will occur when users running Outlook 2007 or Outlook 2010 connect to the Exchange Server. Microsoft provide a KB for this issue here

However the KB references a standard Exchange Server installation and not SBS Server and so the reference to IIS is incorrect.

Ensure that you change the reference to the Default Web Site to the the IIS site that contains the Exchange IIS information, SBS Web Applications.

My server for example is as follows

Set-WebServicesVirtualDirectory -Identity "SBIZ\EWS (SBS Web Applications)" -InternalUrl

Set-OABVirtualDirectory -Identity "SBIZ\oab (SBS Web Applications)" -InternalUrl

Set-UMVirtualDirectory -Identity "SBIZ\unifiedmessaging (SBS Web Applications)" -InternalUrl
