Hello, I have Test lab Environment with Windows 2008 domain and Exchange 2007. Additionally 1 XP Domain Client. I have successfully installed CA on DC and issued a certificate for exchange. I successfully imported certificate on Exchange 2007 But but still I am encountered with Certificate Error page in IE 7 and IE 8. Any Advice. Thanks

I got a hint. I issued a certificate by the name ex2007.testlab,com when I accessing by this URL https://ex2007.testlab.com I am not facing certifcate error issue But when I access by the simple URL https://testlabmail I received the certificate error message. Any suggestion Thanks

Any help.

Hi, Please verify if the certificate has been under Trusted Root Certificate Authority. Also please try to install the certificate to the client computer After that please test the issue again.Xiu Zhang TechNet Community Support

Thank Xiu for your response. I have resolved the issue by the removing the certrificate and reinstalling by the adding dns name testlabmail. Thanks.
