Email without attachment but size indicates attachment?

    Someone sent me an email with an attachment (family-related newsletter) but
    when I go to my Inbox it does not show the attachment as the paperclip.
    The size of the email does indeed indicate an attachment at about 6 MB.

    If I go to the email's Properties => Details, I click on Message Source and
    get this huge amount of data starting with:

    Content-type: application/ms-tnef; name=winmail.dat
    Content-transfer-encoding: base64
    Content-disposition: attachment; filename=winmail.dat

    Why did the data not come across as an attachment and is there a way to
    somehow make the data a real attachment?

    Sounds like you don't have a decoder for base64 installed, so Windows
    Mail can't decode it and make it an attachment. Sorry, I'm not aware of
    where to get one.

  3. The mail was sent from Outlook, using Outlook's RTF format. Outlook is the
    only program I know or that can decoder that format. Ask the sender to
    please use plain text when sending to people who do not have Outlook.

  4. As Frank says, this email was sent from Office Outlook in Rich Text Format.
    The ONLY program able to read RTF formatting is Outlook, ALL other email
    clients will either get a "Winmail.dat" attachment that can't be opened, or
    no attachment at all. The fix is to NOT use RTF and use either HTML or
    Plain Text as the default message format.

    The sender said he zipped it before sending (which doesn't sound right
    according to what you guys have just said).
    The sender has since just sent as-is (non-zipped) and it did come across as
    an attachment and readable.

  6. It's still an attachment and Outlook screws up any attachment when using its
    RTF format.
