Exchange 2007 Certificate Error

We started getting errors in Outlook "The secutiry certificate has expired or is not yet valid."  So, I went to Exchange Management Shell and created a new certificate using the following cmdlet: "Get-ExchangeCertificate -thumbprint 123456.... | New-ExchangeCertificate."  I, then used the Enable cmdlet with the new thumbprint and typed in SMTP as the Service name.  But, Outlook is still using the old certificate and is still giving the certificate error.  What am I doing wrong?  How do we get Exchange to use the new certificate?

run this and check how many certificates are there and what are the services enabled for those

Get-Exchangecertificate

make sure you enabled services for the new certificate. And delete the expired certificate

Using IIS, I removed the certificate, but somehow its still using it.  When I click on certificate details (on the error message) it shows me the expired certificate.

Increase your protection from Zero Day threats!

Running two Antivirus' is never a good idea.
Taking advantage of Multiple Security layers on the other hand can often save your hide.

But before doing all this once restart the TRANSPORT service and check for the errors in event log.
If you get any post them here..

OK...now Exchange is using the new certificate.
Had to Install to Trusted Authorities.
Now were getting "The name on the security certificate is invalid...."

Ok on the top you must see the option to see the certificate.
check that once and see that you installed for that only.
Also see this once.
