SYMPTOMS

Consider the following scenario:
  • You receive a MIME or Secure MIME (SMIME) document in Microsoft BizTalk Server 2006 or in Microsoft BizTalk Server 2006 R2 or in Microsoft BizTalk Server 2009.
  • The MIME or SMIME document contains two or more attachments that have the same name.
In this scenario, the document is suspended. Additionally, an error message that resembles the following is logged in the Application log:

Event Type: Error
Event Source: BizTalk Server 2006
Event Category:BizTalk Server 2006
Event ID: 5753
Description: A message received by adapter "<adapter>" on receive location "<receive location>" with URI "<URI>" is suspended.
Error details: Item has already been added.
Key in dictionary: '<name of the duplicate attachment>'
Key being added: '<name of the duplicate attachment>'
MessageID: {<Message ID>}
InstanceID: {<Instance ID>}

This problem may occur if one of the following conditions is true:
  • You use a Post Office Protocol 3 (POP3) adapter to retrieve data from a server that houses POP3.
  • You use a file adapter to receive the .eml files from a file location, and you use a pipeline that uses a MIME/SMIME decoder to process the incoming files.

CAUSE

This problem occurs because of an error in the MIME/SMIME decoder component of BizTalk Server 2006 or of BizTalk Server 2006 R2 or of BizTalk Server 2009.

RESOLUTION

To resolve this problem, apply the following hotfix. After you apply this hotfix, the MIME/SMIME decoder adds a sequence number and a GUID to the attachment name for MIME/SMIME documents that are received. Then, the attachment name is in the format of ORIGINALNAME-%n%%GUID%, where: %n% represents the attachment number.

Note Because the maximum size of the promoted property is 255 characters, the name may be truncated.
