INTRODUCTION

To enable secure client access from the Internet to Microsoft Exchange Server, Microsoft works with public X.509 certification authorities (CAs) to make sure that you can obtain the certificates that you require to use the Domain Security feature.

Microsoft also works with CAs to make sure that you can get the certificates that you require to use Microsoft Lync Server.

More information

Many public certification authorities have created Exchange-specific websites that provide relevant documentation about their services. The documentation that is provided includes steps to complete the following tasks:
  • Complete the certificate enrollment process
  • Deploy the Domain Security feature
  • Enable secure client access from the Internet
The following table includes the names and websites for the certification authorities that issue Unified Communications certificates for Exchange Server and Lync Server.
