Hi Zakaria, If you want to renew self-signed certificate on Exchange 2007 SP2, you can follow these steps to achieve the goal: 1. Run Get-ExchangeCertificate | fl and note down the Thumbprint of certificate. 2. Run Get-ExchangeCertificate –Thumbprint “Thumbprint of certificate (which you note down)” | New-ExchangeCertificate. 3. Run this command Get-ExchangeCertificate –Thumbprint “Thumbprint of renewed certificate ”|FL to check whether the certificate is renewed. 4. If the certificate has been renewed, you need use this command to enable this renewed certificate for IIS: Enable-ExchangeCertificate –Thumbprint “the renewed certificate’s Thumbprint” –Services IIS 5. Verify all the services are working correctly after renewing and enabling the certificate. 6. Remove old certificate by running this command: Remove-ExchangeCertificate –Thumbprint “Thumbprint of old certificate” Here is a related document for you: Certificate Use in Exchange Server 2007 http://technet.microsoft.com/en-us/library/bb851505(EXCHG.80).aspx Best Regards, Evan Liu TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
