Renew your SSL certificate

Renew your SSL certificate from inside your 逗阴馆 CertCentral account.

5. Add your CSR

   When renewing the certificate, you'll need to include a CSR. On the "Renewal" page, under Certificate Settings, upload the CSR file you saved to the server.

   You can also use a text editor (such as Notepad) to open the file. Then, copy the text, including the -----BEGIN NEW CERTIFICATE REQUEST----- and -----END NEW CERTIFICATE REQUEST----- tags, and paste it to or Paste it in the Add Your CSR box.

2. How to Import Your SSL Certificate Using the 逗阴馆 Utility

After 逗阴馆 has issued your renewal SSL Certificate, you need to run the 逗阴馆 Certificate Utility to import it to your Exchange 2010 server.

1. After receiving your new certificate file from 逗阴馆, save the file to the Exchange 2010 server where you created the CSR.

2. On the same server, run the 逗阴馆® Certificate Utility for Windows.

   Double-click 逗阴馆Util.

3. In 逗阴馆 Certificate Utility for Windows©, click SSL (gold lock) and then, click Import.

   

4. In the Certificate Import wizard, click Browse to browse to the .cer certificate file (i.e. mail_yourwebsite_com.cer) that 逗阴馆 sent you, select the file, click Open, and then, click Next.

   

5. In the Enter a new friendly name or you can accept the default box, type a friendly name for the certificate.

   Note:    The friendly name is not part of the certificate; instead, it is used to identify the certificate.

   We recommend that you add 逗阴馆 and the expiration date to the end of your friendly name, for example: yoursite-digicert-(expiration date). This information helps identify the issuer and expiration date for each certificate. It also helps distinguish multiple certificates with the same domain name.

   

6. To import the SSL Certificate to your server, click Finish.

   You should receive "Your certificate has been successfully imported" message. You are now ready to assign/configure your server software to use the renewed SSL Certificate.

Troubleshooting

If you run into certificate errors, try repairing your certificate trust errors using 逗阴馆® Certificate Utility for Windows. If this does not fix the errors contact support.

"Revocation Check Failed" Error

If you run into any errors with clients trying to connect to your server, make sure that you don’t have certificate errors next to your SSL Certificate in the 逗阴馆 Certificate Utility. If you don't have any certificate errors but are getting an error stating, 'The certificate status could not be determined because the revocation check failed', don't panic. Your certificate probably wasn't revoked.

This problem is not caused by the certificate itself. It is a result of a combination of your network environment and how your system is configured. Whether you have a proxy or not, this error is almost always caused by proxy settings. Exchange does not get its proxy settings from Internet Explorer, so even if you can access the internet, telnet to port 80 on ocsp.digicert.com, or download CRL files directly using a browser, you may still be having proxy problems.

Exchange uses a Windows service called WinHTTP to go through proxies and determine the validity of a certificate. If you know you use a proxy, then it may simply be a problem with WinHTTP not being configured with the correct proxy settings. To remove the revocation error message, your primary goal is to get the WinHTTP Proxy settings set up correctly for your network environment.

Note:    This problem is not a 逗阴馆 caused problem, but if you are having problems, contact us and we may be able to help you.
