Topic Last Modified: 2005-05-05

This topic contains links to procedures for the following tasks:

• Connecting Exchange 2003 to a non-Exchange messaging system that supports Lightweight Directory Access Protocol (LDAP) and Internet Message Access Protocol version 4 (IMAP4)
  
• Performing semi-automated directory synchronization
  
• Migrating mailboxes from the legacy non-Exchange messaging system to Exchange 2003
  

Note:

In the following procedures, it is assumed that you are running a messaging system that supports Simple Mail Transfer Protocol (SMTP) or X.400 for message transfer. Because no further assumptions can be made about your non-Exchange messaging system, specific details about how to configure your non-Exchange messaging environment cannot be provided. For configuration details, consult the administrator documentation for the non-Exchange messaging system that you want to connect to. For information about how to verify that messages can be transferred to a non-Exchange messaging system through SMTP, see Interoperating with and Migrating from Other Non-Exchange Messaging Systems to Exchange Server 2003.
