Exchange 2000 includes several types of connectors that allow your Exchange 2000 organization to communicate with the messaging systems of other companies. When you use the correct connector, the communication with another messaging system is not visible to the Exchange 2000 user. However, if you install a connector for another messaging system, you must perform additional steps when you back up and restore Exchange 2000.


In Exchange 2000 you can backup and restore connectors to other messaging systems so that your data does not become obsolete.

Exchange 2000 Connectors

The following connectors for other messaging systems are included with Exchange 2000.
  • Lotus Notes. This connector has built-in messaging, directory synchronization, and meeting request capabilities.
  • Microsoft Mail. The Microsoft Mail (MS Mail) connector connects servers that are running Exchange 2000 to servers that are running MS Mail. The directory on the server that is running MS Mail is synchronized to the Microsoft Windows 2000 Active Directory directory service through the MS Mail connector by using the Microsoft Mail Directory Synchronization protocol. One server (it can be either the Exchange 2000 server or the MS Mail server) is configured as a directory synchronization requestor. The other server is configured as a directory synchronization server. The directory synchronization requestor periodically polls the directory synchronization server for any changes to the foreign directory and provides any changes that have occurred to its own directory. The directory synchronization server replies with the changes to its directory and updates its directory with the changes provided by the requestor.
  • Lotus cc:Mail. This connector supports DB8-type cc:Mail post offices. Lotus cc:Mail users are added to Windows 2000 Active Directory as contacts or as mail-enabled users. Directory synchronization is built into the connector, and you do not need any additional files to configure the synchronization.
  • Novell GroupWise. The Novell GroupWise connector provides messaging connectivity, allows mail and directory synchronization between GroupWise and Exchange 2000, and supports calendar functionality such as meeting requests.
Note: For more information about the Lotus Notes connector, Microsoft Mail connector, cc:Mail connector, and Novell GroupWise connector, see Exchange 2000 online Help.

Backing Up and Restoring Exchange 2000 and Connectors to Other Messaging Systems

The following procedure works to back up and restore Exchange 2000 organizations that have installed connectors for other messaging systems:
  1. On a server that is running both Exchange 2000 and one or more of the connectors that are included with Exchange 2000, configure the connectors according to the following instructions, and then verify that the connectors are functional.
    • Microsoft Mail connector. Back up the Microsoft Mail shadow post office that is located in the Connect\Msmcon\Maildata subdirectory, including the shadow post office subdirectories.
    • Lotus cc:Mail connector. You do not have to back up the Ccmcdata directory and subdirectories, because the cc:Mail connector can re-create these after the recovery process. However, you must back up and restore the cc:Mail import files and the cc:Mail export files that are installed on your servers that are running Exchange 2000, because these are external programs that communicate with Lotus cc:Mail.
    • Lotus Notes connector. Back up the Lotus Notes client software, including the software directory and configuration file, such as Notes.ini, on the connector computer. The Lotus Notes client installation program installs the Lotus Notes Windows 2000 Registry setting HKEY_LOCAL_MACHINE\SOFTWARE\Lotus\Notes, which you back up as part of the Windows 2000 System State data in a later step.
    • Novell GroupWise connector. Make sure that the GroupWise Gateway Network Service can be restored correctly.
    • Lotus Notes and Novell GroupWise connectors. Back up the Conndata directory and its subdirectories. After you complete the recovery process, delete the work files *.seq and *.ck in the Conndata directory before you start the Lotus Notes or Novell GroupWise services. The Conndata directory and its subdirectories contain the mapping rules and the correlation tables that are used by the connectors.
    Note: To make sure that your data does not become outdated, back up Conndata\Tables frequently. If the correlation table is corrupted, the connector is re-created, but much of the correlation information is lost.

  2. Back up the Windows 2000 system state data by using the latest Backup utility update that is included with Windows 2000.
  3. Back up the Exchange 2000 storage groups on the server by using the Backup utility that is included with Windows 2000.
  4. Restart the computer and reinstall Windows 2000.

    Select a computer name that is different from the original computer name.
  5. Restore the Windows 2000 system state data on the computer on which you reinstalled Windows, and then restart the computer.
  6. Install Exchange 2000 in disaster recovery mode by typing the following file name at the command prompt:
    Make sure that you select each connector that you previously selected.
  7. After setup is complete, restore all the Exchange 2000 storage groups.

    Note: Click to select the Last Backup Set check box if you have a distinct file, or click to select the Mount database after restore check box to mount the database.
  8. Restart the computer and perform the following procedures for your connector:
    • Microsoft Mail connector: restore Maildata to override the Microsoft Mail shadow post office.
    • cc:Mail connector: restore the cc:Mail import and export files.
    • Lotus Notes connector: restore the Lotus Notes client program on the server and verify that the Windows 2000 Registry setting of the Lotus Notes client works by operating the Lotus Notes client program on the server that is running Lotus Notes.
    • Novell GroupWise connector: after you restore the GroupWise Gateway Network Service, verify that you can read and write files to the GroupWise API directory.
  9. Verify that the restored connectors start.
