winmail.dat (outlook, vsnl.net, gmail)

User B has 3 accounts (corporate email, vsnl.net and gmail).
Corporate email is setup in outlook... vsnl.net and gmail accounts are setup in outlook express.
When user A (using outlook) sends to user B with attachment, outlook (corporate a/c) can receive the attachment as it is. vsnl.net and gmail a/cs receive the attachment as winmail.dat.

User B says that its only from this particular User A that has this issue. He can receive attachment as it is in his vsnl and gmail a/cs from other people.

Winmail.dat is a notorious issue when sending email from Outlook to other clients. Here's a tool to extract attachments from winmail.dat: http://www.biblet.freeserve.co.uk/

One solution that worked for me is to instruct User A to to send the email as Plain Text.

If User A uses Exchange, here's Microsoft's take on the issue: http://support.microsoft.com/kb/138053

Hi, for the settings to plain text...
other than under tools->options->mail format->message format,
there is this button called 'internet format', do i need to set anything in there?

if i ask user B to setup his vsnl and gmail a/cs in outlook, will that help to resolve the issue as well?

i tired on my own a/c by setting user B 'send options' to HTML only.
he managed to receive my attachment. which is why this is the puzzling thing. i send to him in html format and he able to receive it.
Indeed, the problem does not occur in majority of cases - otherwise, half the Internet would not be able to receive attachments from Outlook.

It appears that it is linked to sending email in RTF format, so using HTML might work as well as plain text.

When you select RTF format, Outlook uses TNEF to encode the message. For plainp-text or HTML it uses MIME. TNEF is Microsoft-proprietary format, hence the compatiblity issues. MIME is the Internet standard that everybody understands. http://en.wikipedia.org/wiki/Transport_Neutral_Encapsulation_Format

Hope this helps...
Any feedback on this issue?
