Microsoft Exchange could not find a certificate that contains the domain name EXCH.xrds.org in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Barracuda Spam Filter with a FQDN parameter of EXCH.xrds.org. 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. Anybody know how to fix this

Hello, First you have a double post, please remove the other one here: http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/c0256bc4-25cb-41cc-a764-5f404d70b344 To solve this event, open the Exchang power shell, run this command (I assume your server name is EXCH, and your internal domain is xrds.local, and your external domain is xrds.org just as an example) New-ExchangeCertificate -KeySize 2048 -SubjectName "CN=EXCH" -DomainName EXCH, EXCH.xrds.local, EXCH.xrds.org -PrivateKeyExportable $True | Enable-ExchangeCertificate -Services SMTP This will generate a new selfsigned certificate with the required domains associated, and enable it for SMTP restart the Transport service, and any other required services, and make sure things are going fine, then you can remove the old selfsigned certificate. If you have EDGE server, check the synchronization, you may need to re generate EDGE Sync file. Ibrahim Al Masry http://www.ibra.me/
