SSL trust error in Outlook 2013 The security certificate was issued by a company you have not chosen to trust. View the certificate to determine whether you want to trust the certifying authority. If you choose Yes to proceed you may also encounter this additional error message. Error: Outlook is unable to connect to the proxy server There is a problem with the proxy server's security certificate. The security certificate is not from a trusted certifying authority. Outlook is unable to connect to the proxy server [servername] (Error Code 8). This error occurs when the Exchange server is configured with a self-signed SSL certificate. Outlook makes connections to the Exchange server over HTTPS and therefore must trust the SSL certificate that is configured on the server, otherwise it will display those error messages to the end user. To resolve the issue install a valid SSL certificate on the Exchange server from a trusted certificate authority. See Exchange Server 2013 SSL certificates for more details on this as well as step by step instructions.

Reply Atul says March 15, 2013 at 11:43 pm well , is there any way to resolve issue without buying an external certificate from trusted certificate authorities? for more than 3 years I am I have not faced this issue.. Reply Paul Cunningham says March 17, 2013 at 8:04 am A certificate has to be trusted for it to be valid. If you don't want to use a commercial CA then you can look into using a private CA instead. However if you don't already have a private CA in place then commercial CA's are the best way to go. Reply Atul says March 17, 2013 at 2:57 pm well terms private and commercial sh
