No valid SMTP Transport Layer Security (TLS) certificate

[josh2009]

I get event id 12016 in the app log.
There is no valid SMTP Transport Layer Security (TLS) certificate for the FQDN of SERVER.xxx.local
have renewed the self signed cert using command
Get-ExchangeCertificate –thumbprint "xxxxx" | New-ExchangeCertificate Have deleted the expired cert.

we have a valid go daddy cert enabled for imap, iis, pop and smtp

how can i resolve this error?

Thanks.

Check your send and receive connectors. All of them should use the same FQDN on the first tab in their properties as you have on your cert. If you use some other name besides the name of your cert on that first tab, you'll get the error you described. That field has to always match a name on a cert.

the sbs internet receive connector has remote.xxx.ie - go daddy cert name.
the default server receieve connector has server.xxx.local.
when i try to change it to remote.xxx.ie I get:

When the AuthMechanism parameter on a Receive connector is set to the value ExchangeServer, you must set the FQDN parameter on the Receive connector to one of the following values: the FQDN of the transport server "SERVER.xxx.local", the NetBIOS name of the transport server "SERVER", or $null.
