SYMPTOMS
The following behaviors occur in a mixed-mode environment with Exchange 2000 Server and Exchange Server 5.5:  Mailbox users on the Exchange Server 5.5 cannot reply or send messages to contacts brought in to the global address list (GAL) by a connector to a foreign mail system on an Exchange 2000 server. They will receive an non-delivery receipt (NDR) similar to the following message:

From: System Administrator

Sent: Wednesday, January 31, 2001 12:17 PM

To:

Subject: Undeliverable: RE: test

Your message did not reach some or all of the intended recipients.

Subject: RE: test

Sent: 1/31/2001 12:17 PM

The following recipient(s) could not be reached:

on 1/31/2001 12:17 PM

The recipient name is not recognized

The MTS-ID of the original message is: c=US;a= ;p=microsoft;l= -010131181649Z-10

MSEXCH:MSExchangeMTA: :

 As viewed from the Exchange 5.5. Administrator, the custom recipient has no X.400 address. As viewed from the Exchange 2000 System Administrator, the contact has no X.400 address. If an X.400 address is added to the contact and the Active Directory Connector (ADC) replicates this to the Exchange 5.5 server, new messages and replies function correctly. When the administrator runs the Recipient Update Service, the following error appears in the Application log on the Exchange 2000 server:

Event Type: Error

Event Source: MSExchangeSA

Event Category: General

Event ID: 2027

Date: 1/31/2001

Time: 3:30:06 PM

User: N/A

Computer: ALANEW10

Description:

Unable to generate the e-mail address. Unable to load address module 'C:\Program Files\Exchsrvr\address\ \i386\ibmpxgen.dll' for address type ' '. Error 0xc007007e.

CAUSE
This behavior occurs because there is no .dll file to generate the proxy address for either the Microsoft Exchange Connector for SNADS or Microsoft Exchange Connector for IBM OfficeVision/VM (PROFS); the X.400 address is also not generated.



RESOLUTION
To resolve this behavior:
 * 1) Navigate to the \Exchsrvr\Address directory.
 * 2) Create a directory for the Exchange SNADS Connector and/or the Exchange PROFS Connector in the Address directory of the Exchange 2000 server.
 * 3) Create an \I386 directory under the Exchange SNADS and/or PROFS Connector directory.
 * 4) Copy the Ibmpxgen.dll file from the Exchange 5.5 server with the Exchange SNADS or PROFS Connector to the new directory. The Ibmpxgen.dll file can be found in the Address\Snads\i386 directory of the Exchange 5.5 server.
