I recently used exmerge to import mailboxes from an external hosted Exchange 2003 service to our new internal Exchange 2003 server. The two Exchange servers are in different AD forests.
In order to allow users to reply to migrated email messages, I added a custom X500 address to each recipient with the information from the external hosted Exchange server. The legacyExchangeDN value for each recipient points to the local Exchange server.
The following error message is appearing in the application log, and replies to migrated messages are failing with a NDR.
Event Type: Error
Event Source: MSExchangeSA
Event Category: General
Event ID: 2035
Time: 8:21:57 PM
The e-mail address description object in the Microsoft Exchange directory for the 'X500' address type on 'i386' machines is missing.
I checked the recipient address templates in System Manager and there is no entry for X.500.
How do I enable Exchange 2003 sp2 to recognize and generate X.500 addresses?
