SYMPTOMS
After the Microsoft Exchange 2000 Recipient Update Service (RUS) runs, Active Directory user accounts may have multiple X.400 addresses.



CAUSE
This problem occurs when you modify the last 5 characters of the Last Name attribute of an Active Directory user account, where the Last Name attribute contains 40 or more identical characters. In this scenario, the Exchange 2000 proxy validation process may not be able to interpret the current X.400 address as valid for the user account, and therefore it creates a new X.400 address for the Active Directory user account.
