Common Name (required)

Your Exchange server's fully qualified domain name. If you are not sure what name to use, please refer to the notes below.

To secure mail.example.com, your common name or one of your subject alternative names must be mail.example.com.

Less commonly, you may also enter the IP address or short name of your internal server. For example, appserver1 or 192.168.1.200.
Subject Alternative Names (optional)

One per line, or comma separated, either way is fine.

Microsoft recommends including your Exchange server's full public domain name (eg mail.yourdomain.com) and autodiscover.yourdomain.com.

If your company has a separate internal active diretory domain you can also include the names users will connect with to access their mail (e.g. mail.internaldomain.com, CAS.internaldomain.com).
Department (optional)

Many people leave this field blank. This is the department within your organization which you want to appear in the certificate. It will be listed in the certificate's subject as Organizational Unit, or "ou."

Common examples:

  • Web Administration
  • Web Security
  • Marketing
  • Engineering
  • Information Technology
City

The city where your organization is legally located.
State or Province

The state or province where your organization is legally located.
State

Your IP appears to be in the USA, so we've provided a States dropdown list for your convenience. But if you're creating a CSR for a location outside of the USA, you can enter anything into the list. It will accept any state name you type.
Country

We guessed your country based on your IP address, but if we guessed wrong, please choose the correct country. If your country does not appear in this list, there is a chance we cannot issue certificates to organizations in your country.
Organization name

The exact legal name of your organization. Example: "DigiCert, Inc."

Less commonly, if you do not have a legal registered organization name, you must enter your own full name here.
Key Size

Key sizes smaller than 2048 are considered insecure.

What Subject Alternate Names Should I Include?

Our page on choosing SAN names in Exchange 2010 can help you know what names to include in your certificate request.

What kind of SSL certificate should I buy?

When you want SSL for Exchange 2010, your choices are usually single certificates and SAN certificates—also known as Unified Communications SSL certificates.

SAN Certificates allow you to include Subject Alternative Names in your SSL Certificate so you can protect multiple URLs with just one certificate. Microsoft recommends Unified Communications Certificates because they greatly simplify your SSL configuration.
