Connecting to Other Messaging Systems

Connectors and Active Directory

Unlike previous versions, Exchange 2000 Server does not include its own directory service. Exchange 2000 Server is now integrated with the directory in Windows 2000, called Active Directory. Active Directory provides functionality such as the global address list, address book views, and offline address books.

During directory synchronization, when connectors import user information from other messaging systems into Exchange, they write the information to Active Directory. Active Directory stores information differently than the directory service used by Exchange 5.5. One important difference between the Exchange 5.5 and Exchange 2000 is that with Exchange 5.5, recipients from other messaging systems are stored in Exchange as custom recipients. Custom recipients cannot access Windows NT resources. With Exchange 2000, you can choose to create either contact or user objects in Active Directory; that is, you can provide a logon account (and therefore, access to Windows 2000 resources) to recipients who have mailboxes on other messaging systems.

Cleaning Duplicates in Active Directory

Duplicate accounts may be created by directory synchronization, migration from another messaging system, or upgrading a Windows NT domain. To help you manage duplicate user accounts, Exchange provides Active Directory Account Cleanup Wizard. The wizard searches a Windows 2000 forest for possible duplicate Windows 2000 accounts and allows you to merge duplicate accounts. Active Directory Account Cleanup Wizard is located in the Support\Adclean\I386 directory on the Exchange compact disc. The file name is Adclean.exe.
