Exchange Server 2010: Generate CSRs (Certificate Signing Requests)

To complete your online request form for an SSL, you need a Certificate Signing Request (CSR). Follow these instructions to generate a CSR for your website. After you generate your CSR, copy and paste it into the CSR field on the SSL certificate request page.

Warning: If you need to secure more than one domain name, we recommend that you use a Multiple Domain Unified Communications Certificates (UCC) with your Microsoft® Exchange Server.
