Hi James, I tried the command given by you in the below mail. We have two hub servers. On both the Hub servers, verisign certificate is installed.
But no self signed certificate exists on one server, where as on the second server there are two self signed certificate exists but both of them showing as invalid in status as they are expired. Do we need to have internal self signed certificate as well when
we have external certificate installed. Do we need to renew those internal self signed certificate to make the SMTP working on MAC mail. These are the details I got for internal self signed certificates. On second server there is no certificate like this. ==========================================================

James Chong This can also happen if your send\receive connectors FQDN (specify the fqdn this connector will provide in response to HELO or EHLO) does not match your cert name as
event indicates; but since you mentioned that it expired; it’s probably related to that.

You need to enable the cert that has your netbios name. The cert needs to be valid and not expired.

On Behalf Of Hi James, We are getting the below mentioned error in the event logs. Event ID for this 12014 and Event Source is MSExchange Tranport.
============================================
Microsoft Exchange couldn't find a certificate that contains the domain name <server name> in the personal store on the
local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Outgoing with a FQDN parameter of <server name>. 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. ==========================================================
When I search for the list of certificates on the Hub server, it shows me a long list of certificates. How do I check which certificate
I had to install or renew. Regards, From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx]
On Behalf Of James Chong If you did not get a SAN cert that included your netbios name, then yes. You need to run new-exchangecertificate to generate request; upload to your CA server. Download
the cert , import the cert, and enable the cert for IMAP. James Chong

On Behalf Of Hi, We have exchange 2007 in out network. Few days back we have renewed our SSL certificate on Exchange Servers at different sites, those were purchased from Verisign. Everything
was working fine, till few users reported problem in connecting to mail server using IMAP, MAC, thunderbird etc. We have checked on the server it is giving error for some internal self signed certificate expiry. Do we need to re-install the self signed certificate
for SMTP as users are not able to send emails using the MAC, Thunderbird etc. Please suggest.
