SBS 2011 Exchange certificates issue - SMTP does not accept mails

Hello,

I'm having an issue with a SBS I installed 2 years ago.

The self-signed certifcates have been expired, and Outlook gave an error on every connection.

I have searched a solution an found one that rebuilt the certificates using these commands:

certreq -new request.inf certnew.req
certreq -submit certnew.req certnew.cer
certreq -accept certnew.cer

and then import this certificate.
After this, and a reboot, the SMTP doesn't accepted any mail.

I have tried several things, but nothing. SMTP refuses to accept mails.

What can I do?

Thank you very much!

Hello,

a correction: the issue is half solved: the SBS wizard had removed the IP range of the local network from the connectors configuration.

The server now accepts the mail, but I would like to fix also the certificates.

Thank you very much for any help!

Please refer article http://exchangeserverpro.com/configure-an-ssl-certificate-for-exchange-server-2010/

Follow section "Assign the New Certificate to Exchange Server 2010" to conifgure certificate for SMTP.

After that check the mail flow,

Hello,

thank you very much for your answer!

Should I remove old certificates first or let them alone on the server?
