Setting up Exchange configuration in Exchange 2010 & 2013

Setting up the configuration in Exchange 2010 and 2013 configuration will vary depending on your environment. You will need to know and select the Exchange configuration that best works for you and your organization. If you need more support on how the Exchange configuration services best fits you and your environment you will need to contact Microsoft Support.

Below is a simplified explanation of each item.

• Federated Sharing — Select if you want to use your certificate for Federated Delegation.
• Client Access server (Outlook Web App) — Select if you have Outlook Web App on the Internet, and then enter the domain names you use to access Outlook Web App.
• Client Access server (Exchange ActiveSync) — Select if ActiveSync is enabled, and then enter the domain name you use to access ActiveSync.
• Client Access server (Web Services, Outlook Anywhere, and Autodiscover) — Select if you are using Exchange Web Services or Outlook Anywhere, and then enter the hostname for your organization. You also need to select if you want the Autodiscover service for the Internet. If you do, select a long or short URL, and then enter the domain name you use to access it.
• Client Access server (POP/IMAP) — Select if you are using POP/IMAP services internally and/or externally. Enter the domain name you use to access both POP and IMAP services.
• Unified Messaging server — Select if you want to use a Self-signed or Public certificate with Unified Messaging, and then enter the fully qualified domain name (FQDN) you use for your Unified Messaging servers.
• Hub Transport server — Select if you want to use TLS to help secure Internet mail or if you want to use the server for POP/IMAP client submission. For either selection, you need to enter the FQDN of your server.
• Legacy Exchange Server — Select if you want to use your legacy domain names and then enter the domain name associated with your legacy servers.

Each one of these services is associated with a domain name that will be required for enrollment of a UC/SAN certificate. 

Note: Due to Cab Forum and standards in the industry internal or .local domains are no longer issued on a certificate.
