Add second domain to exchange 2007 certificate

We have a exchange 2007 mail server (part of SBS 2008). I added a new accepted domain and given the users an new email address in the new domain. I also made the new email address primary.

Now I get the following error in the event log:
Microsoft Exchange could not find a certificate that contains the domain name mail.new-domain.com in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Send Connector with a FQDN parameter of mail.new-domain.com. If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key.

I think I have to create a certificate for the new domain and enable the SMTP service for it. Or I can add the new domain to the existing certificate which is now used bij mail.old-domain.com.

I have tried to make a certificate request file (.csr) but i don't know how to get from there.

It has to be a self signed certificate.

All help is very welcome.

You can't add the domain name in existing certificate for that you have to reissue the certificate with multiple domain.

To create a self sign certificate please refer below links.





Shell command for create self sing certificate :

New-ExchangeCertificate -SubjectName "c=US, o=abc Bank, cn=mail1.abc.com" -DomainName abc.com, example.com
