Attachment is lost or cannot be opened 

---

Description

If a consumer composes a text only message using Microsoft Outlook 98 in an RTF format, then the messaging software displays the text in the body of the message and also claims that there is an attachment.

If a consumer composes a text message and attaches a file (attachment) using Microsoft Outlook 98 in an RTF format, then the messaging software displays the text in the body of the message and claims that there is no attachment.

Both of these issues are related. When a consumer sends a message in an RTF format using Microsoft Outlook 98, the message is bundled in the MIME type application/ms-tnef. The messaging software does not understand the application/ms-tnef MIME type, thus the incorrect behavior occurs.

To determine if a message is bundled in the MIME type application/ms-tnef , look in the message database.
