XCLN: Win: Encrypted Messages Do Not Display Attachment Icon

• Microsoft Exchange Windows 95/98 client, versions 4.0, 5.0
• Microsoft Exchange Windows 3.x client, versions 4.0, 5.0
• Microsoft Exchange Windows NT client, versions 4.0, 5.0

SYMPTOMS

When you receive a signed and sealed (encrypted) message with an attachment, the icon indicating that the message has an attachment does not appear. However, when you forward that message without encryption, the paper clip icon (which denotes an attachment) will appear.

CAUSE

An encrypted message has its properties, including attachments, removed. All that remains is the encrypted TNEF (which contains the properties that were encrypted). This means that the Exchange client does not know that an encrypted message contained attachments because the attachment properties have been deleted.
