How to Install SSL/TLS Certificate in Microsoft Exchange 2016

The following instructions will guide you through the SSL installation process on Microsoft Exchange 2013 EAC. If you still have not generated your certificate and completed the validation process, reference our Exchange 2016 CSR Generation Instructions.

What You’ll Need

1. Your server certificate

This is the certificate you received from the CA for your domain. You may have received this via email. If not, you can download it by visiting your Account Dashboard and clicking on your order.

2. Your intermediate certificates

These files allow the devices connecting to your server to identify the issuing CA. There may be more than one of these certificates. If you got your certificate in a ZIP folder, it should also contain the Intermediate certificate(s), which is sometimes referred to as a ‘CA Bundle.’

3. Your private key

This file should be on your server, or in your possession if you generated your CSR from a free generator tool. Neither TheSSLStore nor the Certificate Authority requests or keeps your private key.
