XFOR: Internet Mail Service Attachment Formatting Fails Due to Content-Location Support Added in SP1

ID: Q196849

The information in this article applies to:

Microsoft Exchange Server, version 5.5
Microsoft Mail for PC Networks, version 3.5

SYMPTOMS

Under certain circumstances, when you send messages containing multiple attachments using the Exchange Server 5.5 Service Pack 1 Internet Mail Service, the messages may not arrive correctly formatted for an Microsoft Mail for PC Networks recipient. This can occur when the e-mail is received by the Microsoft Mail (PC) postoffice by means of third-party gateways that lack the ability to handle Content-Location data correctly (RFC 2110).

When viewing the message, using the Exchange, Microsoft Mail (PC), or Outlook client, the attachments are displayed as raw MIME in the body text, and cannot be launched or accessed.

A message containing a single attachment arrives correctly formatted.

CAUSE

The problem is attributable to new functionality, added to Exchange Server 5.5 Service Pack 1, to support Content-Location in the message body. Content-Location is a proposed SMTP standard defined in RFC 2110.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
