Installation Instructions for Microsoft Exchange 2010


This document provides instructions for installing SSL Certificates for Exchange 2010 using the Exchange Management Console. If you are unable to use these instructions for your server, DigiCert recommends that you contact Microsoft.

This solution contains two Methods to install your SSL Certificate:

Method 1: Installing the certificate received via e-mail.

Method 2 (recommended): Installing the certificate downloaded from the Trust Center account.


Method 1: Download and Install SSL certificate sent via e-mail

Step 1: Obtain the SSL certificate sent via email:
           Your certificate will be sent via email. The certificate is imbedded in the body of the email.
           Copy the SSL certificate and make sure to copy the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- header and footer
           Ensure there are no white spaces, extra line breaks or additional characters.
           Use a plain text editor such as Notepad, paste the content of the certificate and save it with extension .txt 

           NOTE: If you selected Microsoft IIS  5.0 or above during enrollment, continue with the installation from here.

           If you are not sure which server software was selected during the enrolment, proceed with Step 2 bellow.
Step 2: Download and Install the Intermediate CAs:
          To download and install the Intermediate CAs follow the steps from this link.

Method 2: Download and Install SSL certificate in PKCS#7 format

Step 1: Download the SSL certificate from Trust Center account:
          Download the certificate from Trust Center by following the steps from this link.

          Make sure you download the certificate in PKCS#7 format and save it with the extension  .txt or .p7b

Step 2: Install SSL Certificate

To install a SSL certificate onto Microsoft Exchange 2010, you will need to use the Exchange Management Shell: 

  1. Start the Exchange Management Console by going to
    Start > Programs > Microsoft Exchange 2010 > Exchange Management Console.
  2. Select "Manage Databases", and then select "Server configuration".
  3. Select the certificate from the center menu (listed by its Friendly Name), and then select "Complete Pending Request" from the "Actions" menu.
  4. Browse to the certificate file, then select Open > Complete.

    NOTE: Occasionally Exchange 2010 will show following error message
    "The source data is corrupted or not properly Base64 encoded."
    Please ignore this error. Although the error may appear,  the certificate often still installs correctly.

  5.          Hit F5 (on the keyboard) to refresh the certificate and verify that it now says "False" under "Self Signed".
             If it still shows "True", the wrong certificate may have been selected or the request may have been generated on a different server. 
             To resolve this issue, create a new CSR on this Exchange server  and replace the certificate.

  6. To enable the certificate, go back to the Exchange Management Console.
  7. Select "Manage Databases", and then select "Server configuration" and click on the link  "Assign Services to Certificate."

  8. Select the services for which the certificate must be enabled then click Next > Assign > Finish.
  9. The certificate is now installed and enabled for use with Exchange 2010.
  10. Test your certificate by connecting to your server with Internet Explorer, ActiveSync, or Outlook. 
    You may also use Digicert SSL Tools.

    NOTE: If you are using ISA 2004 or ISA 2006, you need to reboot your servers. It has been reported that ISA services won't send
    the intermediate certificate until after a reboot.
