Installing a Security Certificate for Exchange 2007 still shows original self signed certificate.

We processed and received back a Security Certificate for our Exchange Server.

Since installing per instructions the exchange server still links to the original self-signed certificate - which it shouldn't!

From outside we use webmail.domain.com to access the server (via OWA)
Internally we use servername.netbiosdomainname.local

This is the layout of the issued certificate

Primary domain name = domain.com

Sans list

1 - servername.netbiosdomainname.local
2 - domain.com
3 - webmail.domain.com


Should we have: 4 - servername (by itself)?

By running the below in powershell:
C:\>Get-ExchangeCertificate -DomainName servername.netbiosdomainname.local

It comes up with

print                                Services   Subject
-----                                --------   -------
C630********328E5342FF66D98A621BC0E  ..U..      CN=domainname.com
05E********BABE77335455321F7FF1498  IPUWS      CN=servername
4A821D31FE********73A8759E44B972BDA  IPU.S      CN=servername

Seems like the certificate has not been enabled for the services they n

Enabling the Exchange Certificate

Enable-ExchangeCertificate -thumb 484152332E6CD3F9864CEB933BC64867DF29BB0B Services IIS, SMTP, POP, IMAP

If you now look at OWA, you will see the newly assigned Certificate running on Site.

As good housekeeping, it would be good practice to remove the un-neccesary certificates to aid easier administration at a later date.eed to use.

Yippee!!!!!!

Thanks - will e-mail Comodo to let them know what the issue was.

Their instructions stated:
Import-ExchangeCertificate -Path c:\exchange.comodo.com.crt | Enable-ExchangeCertificate -Services "SMTP, POP, IMAP, IIS"

Which obviously doesn't allow a force overwriting of the certificate assigned.
