Event ID 12017
This is the error I'm getting: Event Type: Warning Event Source: MSExchangeTransport Event Category: TransportService Event ID: 12017 Date: 8/24/2010 Time: 8:25:42 AM User: N/A Computer: EGVHTCA01 Description: An internal transport certificate will expire soon. Thumbprint:E3AD0D5A7D61460D9D05433E9FA6663B6CD0AB6B, hours remaining: 62 For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Okay I know there are others asking about this cert and how to renew it. This is the link I’m going to and plan to follow tonight will I try to renew it http://exchangepedia.com/2008/01/exchange-server-2007-renewing-the-self-signed-certificate.html My question is, is it as simple as it appears? Will it affect anything else? 2 months ago we got a go daddy cert for OWA. I just want to make sure that I don’t break anything else. Will the end user notice anything? This is my first time doing this and we have about 2200 mailboxes and I get paranoid whenever I need to make a change to exchange. Thanks for any advice!

You need to have Exchange Server Administrator role and local Administrators group for the target server to run New-ExchangeCertificate cmdlet. New-ExchangeCertificate http://technet.microsoft.com/en-us/library/aa998327.aspx You can refer below article while renewing selfsigned certificate... Exchange Server 2007: Renewing the self-signed certificate http://exchangepedia.com/blog/2008/01/exchange-server-2007-renewing-self.html I hope this will help you. Regards. Shafaquat Ali.

Hi, First please try to use get-exchangecertificate |fl to check the "NotBefore" value for the certificate. Since it is a internal transport certificate, we can just renew the certificate. More related information to share with you: The internal transport certificate will expire soon http://technet.microsoft.com/en-us/library/bb217963(EXCHG.80).aspx Note: Please carefully note the value for "CertificateDomains" of the certificate.
