This topic explains how to use the Active Directory Service Interfaces (ADSI) Edit snap-in to change the proxy address of one of the objects specified in Event ID 9514.

An event that resembles the following event may be logged in the Application log on a computer that is running Microsoft Exchange Server 2007:

Event Type: Warning

Event Source: MSExchangeIS

Event Category: General

Event ID: 9514

Computer: Exchange_Server_Name

Description: Two objects in the directory have the same proxy - dc=com/dc=domain/ou=OU_Name/cn=Object1 and dc=com/dc=domain/ou=OU_Name//cn=Object2

You may receive this warning if you have two identical proxy addresses in your organization. This issue may occur if one or more objects are updated simultaneously from different management consoles that connect to different domain controllers. Additionally, mail flow to the objects that are specified in the event description may be disrupted.


To resolve this issue, use ADSI Edit to change the proxy address of one of the objects specified in the event description.

Before You Begin

To perform this procedure, the account you use must be delegated the following:

  • Exchange Organization Administrator role and local Administrators group for the target server

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

ADSI Edit can be run from a client computer or server. The computer does not have to be a member of a domain, but the user must have the rights to view and edit the Active Directory directory service domain to which the user is connecting. For more information about how to use ADSI Edit, see Adsiedit Overview.

  If you use ADSI Edit or any other Lightweight Directory Access Protocol (LDAP) version 3 client, and you incorrectly modify the attributes of Active Directory objects, serious problems may occur. These problems may require you to reinstall Windows Server 2003, Microsoft Exchange 2007, or both Windows Server 2003 and Exchange 2007. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.
