XCCC: You Cannot Open Macintosh Attachments in Outlook Web Access

When you view a message in Microsoft Outlook Web Access (OWA), a file attachment may appear to be significantly smaller than it actually is, and you cannot open the attachment.

This problem occurs because the attachment was sent by a Macintosh client.

To work around this problem, use either of the following two methods:

�	Use Windows file extensions. For example, name an Exchange Server file "Workbook.xls" instead of naming it "workbook."
�	Use another Macintosh e-mail client to open the message and attachment, such as Microsoft Outlook or Microsoft Outlook Express.

Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.

The Exchange message store stores these file attachments in two pieces: a resource record, and a data record. In this problem, OWA cannot display the resource record and because of this, it seems that the attachment is lost but it still exists in the information store. Opening the message by using another e-mail client still works properly.
