Renewing expired Self-signed Exchange 2007 certificate... still getting warning in Outlook

I've got a client running Exchange Server 2007.  The self-signed certificate expired on Aug 13.  One of the users sent me a screen shot of the certificate info showing the serial number etc.  I did the standard Exchange Management Console commands, renewing the certificate with the related thumbprint, etc.  As expected I got a prompt re overwriting, to which I said Yes.

The user exited Outlook and re-ran, but still gets the certificate warning, still showing expired on the 13th.

I did this all 2 years ago, and I recall that it went smoothly.  The instructions I followed did not say I had to restart the Exchange services, but do you think that's what's causing this?

Self-signed certificates is not something I do very often, so I'm not really up to speed with it.  I followed Steps 1 and 2 of this page: http://www.ncol.net/how-to-renew-a-self-signed-certificate-in-exchange-server-2007/

Is it necessary to restart the server or Exchange services after this?  Also, is step 3 on the web page I've indicated necessary to renew the certificate?

Hi,

I see you've listed one of the topics as SBS.  If it is SBS 2008 then you need to renew the certificate via the Fix My Network Wizard in the SBS Console. This will find the certificate expiry and renew it.

The new cert will then be assigned to Exchange, IIS and the Remote Desktop Gateway.
