INTRODUCTION

So that you can get 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 need to use the Domain Security feature. 

Microsoft also works with CAs to make sure that you can get the certificates that you need to use Microsoft Office Communications Server.
