Question : SSL Certificate not Updating

I just purchased a brand new certificate to replace my current SSL Certificate that expired over a year ago. Here was the process I followed:

1. Deleted the current certificate
2. Issued a new CSR
3. Obtained a new Cert from RapidSSL
4. Installed the new Cert into IIS for the Default Website

However, when I browse to the outlook web access at https://mail.domain.net it still gives me the Old certificate.

I verified that the new Certificate was installed by Viewing the Certificate under Directory Security in IIS.
I verified that the certificate being used matched what was in the IIS Metabase.xml file.
I also deleted the old Certificate from the machine using the Certificates MMC snapin.
I have even rebooted the machine.

Any help troubleshooting this issue would be appreciated. For whatever reason, the old certificate continues to be presented upon accessing the site.

Answer : SSL Certificate not Updating

Mostly check all DC's in your environment... open the certificate console using MMC and remove all unwanted certificates...
