3.1 Introduction

At this point, you should be familiar with the basic operation of the ADC. To summarize: It is a utility that uses CAs to define instances of synchronization between the Exchange 5.5 Directory Service and the Active Directory. At first glance, its granularity of operation seems limited. From the Exchange 5.5 Directory Service you can select the contents of one or more recipient containers to be synchronized into a single OU in the Active Directory. Similarly, from Active Directory, you select the contents of one or more OUs to be synchronized into a single recipient container in the Exchange 5.5 Directory Service.

Let's explore synchronizing from the Exchange 5.5 Directory Service. In general, if the source recipient container contains only mailbox entries, you must synchronize all of those mailbox entries; if the source recipient container contains only custom recipients, you must synchronize all of those custom recipients. This also pertains to distribution lists. In general, if the source OU contains only user objects, you must synchronize all of those user objects; if the source OU contains only contacts, you must synchronize all of those contacts; and, again, the same is true for groups. However, it is often desirable to synchronize just a subset of the objects from within a recipient container, when synchronizing to the Active Directory, an OU, or the Exchange 5.5 Directory Service. For example, you may wish to exclude Exchange 5.5 mailboxes that are shared between multiple Windows NT4 users and are not associated with...
