An attachment is not visible in OWA when you use the PC-Pine mail client to send an e-mail message and it is forwarded with a MAPI client to an Exchange 2003 mailbox

When you use the PC-Pine e-mail client to create and send a message with an attachment to a Microsoft Exchange Server 2003 mailbox, and then the message is opened and forwarded with a MAPI client to another Exchange 2003 mailbox or the same Exchange 2003 mailbox, the attachment is not visible in Outlook Web Access.

Note This same attachment is visible in Microsoft Outlook 2002 or Microsoft Office Outlook 2003.

When PC-Pine generates a message that has a plain-text body and an attachment, PC-Pine adds the MIME Content-ID property for the attachment. This Content-ID property causes the Exchange mailbox store to treat the attachment as inline. When this message is forwarded, Exchange generates multipart/related MIME instead of multipart/mixed MIME because the attachment appears to be inline. Therefore, attachments appear inline, and an OWA user cannot see the attachment.
