XWEB: File Attachments in OWA Append 2 Extra Bytes CR/LF

ID: Q187994

The information in this article applies to:

Microsoft Outlook Web Access, version 5.5

SYMPTOMS

When you use Outlook Web Access to send a message with a file attachment, the attached file always has two extra characters appended, that is, CR/LF.

CAUSE

The Exupload code missed two hyphens while parsing the HTTP header information. The delimiter used in computation is "\r\n", as opposed to "\r\n--", ignoring the double hyphen and resulting in two extra bytes.

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:
