The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine the value for the gatewayProxy attribute of each recipient policy object. The gatewayProxy attribute represents a valid address space for the recipient policy.

The Exchange Server Analyzer then queries the Active Directory directory service for all objects of the AddrType class. Objects with a class of AddrType represent non-Exchange address types used by the Exchange Address List Service, formerly the Recipient Update Service, to update recipient objects within a domain with specific types of information.

If the Exchange Server Analyzer determines that there is not a corresponding AddrType object for each gatewayProxy value found for a recipient policy, the Exchange Server Analyzer displays an error.

This error means that the address type object for a third-party program, such as a fax program, cannot be located in Active Directory. This may cause the following symptoms:

Product Name


Product Version


Product Build Number


Event ID


Event Source




Symbolic Name


Message Text

The e-mail address description object in the Microsoft Exchange directory for the '%1' address type on '%2' machines is missing.

To address this error, use ADSI Edit or a similar tool to remove the missing address type from the gatewayProxy attribute of the recipient policy.

If you incorrectly modify the attributes of Active Directory objects when you use ADSI Edit, the LDP tool, or another LDAP version 3 client, you may cause serious problems. These problems may require that you reinstall Microsoft Windows Server™ 2003, Exchange Server 2003, or both. Modify Active Directory object attributes at your own risk.

  7. Click OK to apply the change.

  8. Repeat steps 5, 6, and 7 for each recipient policy.

  9. Click OK to close the Properties window.
