Hi,

It happened again, Outllook creates a mail with an attachment and Outlook Express sees no attachment, just the body of the mail. I'm now running the latest Windows Live Mail 2011 on my Windows 7 computer and it cannot see an attachment either.

It seems Outlook has a weird way of SOMETIMES inserting attachments into a mail that only Outlook understands and that even the most modern regular mail program Microsoft makes does not understand. The funt thing is, it only happens SOMETIMES, not everytime.

In a normal mail where I can open the attachment there wil be a multipart mail with several parts for:
Content-Type: multipart/alternative;
- Content-Type: text/plain;
charset="us-ascii"
Content-Transfer-Encoding: 7bit
- Content-Type: text/html;
charset="us-ascii"
Content-Transfer-Encoding: quoted-printable
-

and finaly:
Content-Type: application/octet-stream;
name="tio.zio"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="tio.zio"
- with the file I want to get.

In the mails where there is a problem there is a completly different way the mail is build. There is just these parts:
Content-Type: text/plain;
charset="us-ascii"
Content-Transfer-Encoding: 7bit
- Content-Type: application/ms-tnef;
name="winmail.dat"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="winmail.dat"

In the winmail.dat is the rest of the mail with everything only Outlook seems to understand. Even the oldest Outlook 2003 I was able to test with these mails has no problem understanding what is happening inside the winmail.dat file but not Liva Mail 2011.

The sending computer is using Outlook 14 (X-Mailer: Microsoft Outlook 14.0) but like I said this seems to have been in Outlook for a long time allready. Could we have either 1) An outlook that does not create these strange mails with a winmail.dat content or 2) Have at least a modern alternative for people using just a mail program (Live Mail 20110 or something like it) that understands this. Mozilla does see the winmail.dat "file" but also does not know what to do with it.

winmail.dat just means that Outlook is sending a Rich Text format message. Outlook Express/Windows Mail can't deal with this. You need to ensure the person using Microsoft Outlook is composing/sending messages in plain text or HTML.

If the person using Microsoft Outlook is composing messages in plain text or HTML format, then the next step is to check the contact records to ensure that they are not marked to receive Outlook Rich Text. This is done by opening the contact record and then double clicking on the email address.

What else... the last time I used a Palm, the chapura software that allows the Palm to sync to Outlook has a nasty habit of marking your contacts to receive Outlook Rich Text only. So keep in mind that if you have 3rd party software that integrates, uses, protects, .etc Outlook data that you might have to eliminate one by one to find the culprit if you find plain text/html messages being changed to Rich Text.

Last but not least, the winmail.dat can be cracked open by fentun (open source program). Shouldn't have a need for it once you learn/educate others on the above, but at least there is an option if you don't want to ask the sender to resend the message.
