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?
