APPLIES TO


 * Microsoft Exchange Server 5.5 Standard Edition

-



This article was previously published under Q241365





SYMPTOMS
Messages meeting the following criteria are undeliverable:
 * They contain an X.400 address that is generated in a personal address book (PAB). -and-


 * The X4.000 address contains a domain-defined attribute (DDA) value that requires unescaping--for example, an at symbol (@), or an exclamation point (!), or an underscore (_), which are entered as (a), (b), or (u) respectively.



CAUSE
The message transfer agent (MTA) will unescape the address but will also unescape the parenthesis if it passes through an X.400 Connector to another system that has the same address space (such as c=US;a= ;p=*;). The address 040 and 041 should be converted by the sending MTA before transmission.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or later:

Component: MTA



WORKAROUND
The user can create a one-off address of

X400:c=US;a= ;p= ;o= ;s=Test with (a);dda\:EMS=TEST\@

or create a custom recipient in the global address list on the sending server. The Address Book Provider (ABP) that processes the address in the message can submit a Distinguished Name (DN) to the server in the P1 content and the parenthesis are not converted.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 3.
