In Exchange 2000 Server Service Pack 1 (SP1), a Migrate from Microsoft Exchange 5.5 option is available. You can also migrate a user account from a command line. If you migrate a user account to Active Directory with a tool such as the Active Directory Migration Tool (ADMT), and then give that user account an Exchange 2000 mailbox, command-line migration may not work, and the following warning and error messages may be logged in the Exchange 2000 Application event log:
Event Type: Error Event Source: MSExchangeMig Event Category: None Event ID: 13002 Date: 2/19/2001 Time: 6:44:25 PM User: N/A Computer: server_name Description: A mailbox could not be found in the target directory with the address 'smtp:firstname.lastname@example.org'.
Event Type: Warning Event Source: MSExchangeMig Event Category: None Event ID: 15000 Date: 2/19/2001 Time: 6:44:13 PM User: N/A Computer: server_name Description: The mailbox for user 'user' already exists, and may have been created during a previous migration. Check for duplicate mail.
This problem can occur because command-line mode migration matches X500 address only, unlike wizard-mode migration, which matches security identifier (SID), X500 address, or both.
To work around this problem, add a source X500 e-mail address to the new account in Active Directory. If you do so, command-line migration then finds the existing account and migrates mail to the new mailbox. You can either use script to add an X500 address to users, or add an X500 address manually. To manually add an X500 address:
In the Active Directory Users and Computers Microsoft Management Console (MMC) snap-in, open the properties of a user that you want to add an X500 address to.
Click the E-mail Addresses tab.
Click New, and then click Custom Address.
In the E-mail address box, paste the "Obj-Dist-Name" from the mailbox object in the Microsoft Exchange Server 5.5 Exchange Server Administrator program (Raw mode).
In the E-mail type box, type X500.
Click OK twice.
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.
Microsoft is researching this problem and will post more information in this article when the information becomes available.
