Install SSL certificate Exchange Server 2013 and 2016

When the request for your SSL certificate is completed, it will be sent to you in a zip file containing, at least, the following files:

  • The CA root certificate
  • One or more intermediate certificates
  • Your certificate
  • A readme file

Save your certificate in an easy to reach location on your server, such as the folder where you saved your CSR. This path will look like the following example:
\\servercertificatesmycertificate.cer

Log in to your Exchange Admin Center environment. Go to the menu option 'Servers' and select the option 'Certificates' in the window on the right side of the screen. Select the friendly name that you entered during the CSR creation process from the table, and click on the button 'complete' on the right side of the screen under the header 'Status'.

A new window will open. In the input field, enter the path to the location of your certificate file. Click 'ok'. Return to the 'Certificates' menu. When your certificate was loaded successfully, the status behind the friendly name will have been changed to 'valid'.

Next, assign the certificate to the appropriate services. Select the friendly name again, and click on the edit icon in the menu directly above the table. A new window will open. Click on 'services' on the left side of the window, and select the services for which you want to use the certificate. You will be able to select any or all of the following options: SMTP, UM call router, IMAP, POP, and IIS. Click 'save'.

Your certificate has now been installed and assigned.
