How do I install an SSL Certificate into Exchange 2013?

Problem

How do I install an SSL Certificate into Microsoft Exchange 2013?

Resolution

This tutorial will be given in 3 parts.  All parts must be completed, but you may find that either Part I and/or Part II may already be completed depending on your security settings and the version of your Windows Server.  If the certificate installation is a renewal of an already existing QuoVadis certificate, you may not need to do Parts I and II as you should already have installed the certificates previously.  The intermediate files must also be installed to ensure that some browsers do not show a certificate error.

Part I - Installing the Intermediate (chaining) Certificate

Part I explains how to install the intermediate files that are required.  QuoVadis uses an intermediate certificate that must be installed on the server to prevent errors in certain browsers.  You may want to go through these steps and if the intermediate certificate is not installed, then please obtain it and follow through with the rest of Part I.  These files can be obtained via the download page in the Trust/Link portal; or if you know which files you require, you can obtain them from the QuoVadis Download Roots & CRL page.

First you must open the Microsoft Management Console.
  1. Click on Start and then Run.

  2. In the Run window, type MMC in the Open: field and click on the OK button.

  3. The Console1 window will appear.

  4. Click on File at the top and then select Add/Remove Snap-in...  Alternatively, you can press Ctrl + M.

  5. In the Add/Remove Snap-in window, click on the Add... button at the bottom.  This will open a third window named Add Standalone Snap-in.

  6. Scroll down in the Add Standalone Snap-in window and find the Certificates component.  Once found, highlight it and click on the Add button at the bottom.  Alternatively, you can double-click on Certificates.

  7. In a new window, you will be given 3 options for which account you want the certificates snap-in to manage.

  8. Select the Computer account radio button and click on the Next button.

  9. At the next screen, click on the Finish button.

  10. Back in the Add Standalone Snap-in window, click on the Close button.

  11. Click on the OK button in the Add/Remove Snap-in window.

Part II - Installing the Root Certificates

Generally, your Windows Server should have the QuoVadis Root certificates installed, however there have been cases where they have not been.  When you install the SSL certificate, if the root certificate is not present, the system will prompt you to trust it, which will also install it.  Part II assumes that you currently have the Microsoft Management Console open.  If you do not, you can find the instructions in Part I of this guide, steps 1-9.
  1. Click on the "+" sign next to Certificates (Local Computer) to expand it (if it isn't already expanded).

  2. Locate and expand the Trusted Root Certification Authorities store and the click on the Certificates folder underneath it.

  3. In In the right hand pane, you should see a list of certificates.  Click on any certificate that you see and press the letter "Q" on your keyboard to fast-track to the QuoVadis root certificates.  Verify that you have the correct QuoVadis Root Certificate(s) installed in the list of certificates in the right hand pane. You can view and/or download the correct QuoVadis Root certificate that is required within the certificate download page within the Trust/Link downloads page of your certificate.. If the certificate is present, then your website should not show any trust errors then you can skip to Part III.  If you do not see this certificate in the Trusted Root Certification Authorities store, then the next steps will guide you through the process of installing this file.
