Event Id 12016 Exchange 2010
Sign in to vote Hi folks, I run SBS 2008 and Exchange 2007 SP3. I looked at my event event id 12016 sbs 2011 viewer today and see that I am getting an event ID: 12016. It says "There is no valid SMTP Transport Layer Security (TLS) certificate for the FQDN of remote.domain.com. The existing new-exchangecertificate task exchange 2010 certificate for that FQDN has expired." When I run the best practices analyzer it mentions this error and says " The SSL certificate of the IMAP4 services on server remote.domain.com expired 06/19/2012. Users may be unable to connect with the server". I've gotten no complaints from users about email issues, but assume I need to address this and fix it. Any idea
Creating A Certificate Or Certificate Request For Tls.
what the right steps are to fix this? I'm afraid to do something without asking the experts for fear of breaking something else. Any direction would be appreciated.

The following connectors match that FQDN: Copier 3, Windows SBS Internet Receive DomainName. You want the 3rd-party cert to be used for external connections, not the self-signed cert, so that's fine. >I cancelled out since I wasn't expecting that message and wasn't sure if I was about to break something.

You can create a new certificate by using the New-ExchangeCertificate task Cause: One of the server installed certificates that has the "S" attribute https://social.technet.microsoft.com/Forums/en-US/694f1c90-2965-49c3-8f54-f61bf5bababe/event-id-12016-ms-exchange-transport?forum=exchangesvrsecuremessaginglegacy (SMTP) has expired, If its the main certificate for the serve then you will need to replace it. However this is common on server that still have a copy of the certificate they self signed and used when exchange was first installed. So you are not using them anyway. Solution I'm assuming that the certificates that have expired are not the ones https://www.petenetlive.com/KB/Article/0000292 you are using in anger, lets make sure. 1. To see what certificates are being used for what. Launch "Exchange Management Shell" > Issue the following command; Get-ExchangeCertificate 2. Above you can see I've got three certificates and they all are being used for SMTP, lets make sure they are all in date. 3. Click Start > mmc {enter} > File > Add/Remove Snap-in > Certificates > Add > Select "Computer account" > Next > Accept the default of "Local computer" > Finish > OK > Expand Certificates > Personal > Certificates. 4. Look down the expiration date section and you can see which ones are out of date, compare this list to original one, and you can see which certificates need removing. 5. You can remove the expired certificated from here by right clicking > Delete. 6. OR, you can delete the certificates from within powershell with the following commandlet; Remove-ExchangeCertificate {thumbnail of certificate} 7. Then press Y and {Enter} to confirm. 8. Either when you are finished you should be looking more like this. Note: Without an SMTP certificate with the FQDN of the serv

Join Now System MS SBS2008 Standard with Exchange 2007 Have started getting the following in the event logs: MSExchangeTransport Error 12016 There is no valid SMTP Transport Layer Security (TLS) certificate for the FQDN of %1. The existing no valid smtp certificate for that FQDN has expired. The continued use of that FQDN will cause mail flow problems. A new certificate that contains the FQDN of %1 should be installed on this server as soon as possible. You can create a new certificate by using the New-ExchangeCertificate task. I have listed all certificates and have six (see below for full details). One certificate is a third party SSL from GoDaddy. Having researched the error, the suggested fix is to run the following : Get-ExchangeCertificate –Thumbprint “F97A00222D212197DB17CDE5453C73746A660CD4"| New-ExchangeCertificate Q1 : How do I know which is the TLS certificate ? I assume it is one of the expired ones so picked the one which only had SMTP listed as the service and was expired. I ran the command above and got an error advising : WARNING: This certificate will not be used for external TLS connections with an FQDN of 'SBS2K8.Servername.local' because the CA-signed certificate with thumbprint '1AAD757C55946730FB1785C944740C8B4B4D6C93' takes precedence.

12016 2/7/2011 6:07:21 AM 2 Event Details: There is no valid SMTP Transport Layer Security (TLS) certificate for the FQDN of SBSERVER.abc.local. The existing certificate for that FQDN has expired. The continued use of that FQDN will cause mail flow problems. A new certificate that contains the FQDN of SBSERVER.abc.local should be installed on this server as soon as possible. You can create a new certificate by using the New-ExchangeCertificate task. Okay… does that mean email will stop? The server will blow up? Will reruning the fixmynetwork wizard fix this? If you had a self signed cert the warning would be a little different… Alert Title Computer Name Last Occurence Total Occurences Leaf certificate expiring SBS.abc.local 1/29/2011 2:15:00 AM 1 The certificate that is helping to secure your Web site traffic will expire in less than two weeks. Before then, run the Fix My Network Wizard from the Connectivity subtab on the Network page of the Windows SBS Console. For those with self signed certs this leaf cert expiration is fixed with the Fix My Network Wizard. For those with trusted ssl certs, it's not so easy. You can either ignore that cryptic warning (not so good) or run a powershell command - I found that the certificate was actually redundant, there was another certificate doing the same job from a third party, so when they imported it they didn't blow away the old certificate. I just ended up removing the certificate. using remove-exchangecertificate -thumbprint thumbprintnumber You can ignore the event, or you can manually renew the cert and then remove the old one, or just remove the old cert. http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_25645034.html
