XWEB: Macintosh Binary Attachments May Not Be Opened in OWA

SYMPTOMS

When you use Outlook Web Access (OWA), files sent from Macintosh users in a binary format may not be able to be opened on an Outlook Web Access client.

Steps to Reproduce the Problem

1. From a Macintosh Exchange client, attach a Macintosh binary text file.
2. Send the message to another user who is using OWA.
3. When this user attempts to open the attached file, he or she will notice the attachment has lost the original icon that associates it with the source application, and the OWA client will not be able to open the file, even if it is saved.
