Chances are that the message was sent using Outlook's RichText format, which
Outlook Express simply can't deal with properly. Ask your correspondents
who use Outlook to only send messages to you using Plain Text format,
especially if there's an attachment.

OT: Your posts' headers (Microsoft Outlook Express 6.00.2900.5512) tell us
that your WinXP SP3 computer is NOT fully patched! Check-in at

updates offered. Then make sure Automatic Updates is enabled & configured
per your wishes; cf. http://support.microsoft.com/kb/306525

Well, I overlooked a difference that might be material. It was more
apparent when I parsed the entirety of both messages, stripping non-header
content

It appears that the original "bad" message bundled the 4 attachments into
one large attachment, presumably a WinZip file. Hotmail presents these as
4
separate attachments; but it also provides the option to download all
attachment, which does open with WinZip.

My "good" message, on the other hand, has 4 individual attachments.

It still is not clear to me why OE does not display the present of at
least
the 1 attachment. But perhaps that is just a limitation of OE, if the
attachment is a WinZip file or "winmail.dat".

(But I am "sure" I have see such attachments presented in OE before.)

The following is all headers of both messages, eliding the content between
them.

----- original message (excerpt) -----

"Joe User" joeu2004 wrote in message
...
I received email in an Hotmail account. When I popped the message into
OE,
the entire message was indeed pulled into OE, but OE did not recognize
the
attachments as such, making it appear that the message had no
attachments.

(But OE displayed only the original body the message. It did not show
the
attachments in their ASCII form either.)

Yet when I tried to isolate the problem by sending a message to my
Hotmail
account, attaching exactly the same (binary) files, then popping the
message into OE, OE had no problem recognizing the attachments and
indicating their presence.

Can anyone explain this?

I have included relevant excerpts from both messages. See below. The
entire messages are too long to include here -- about 5.2 Mbytes each.

I do not see any material difference.

I am using OE 6.00.2900.5512(xpsp.080413-2105), MS Win XP SP3 with IE
6.0.2900.5512.xpsp_sp3_gdr.080814-1236.
