Hi,

Outlook seems to have some limitations on multipart mixed messages. If you
have a message (example below) with 2 parts then only one of them is
displayed, the other is displayed as an attachment. Other clients such as
Thunderbord can cope with this.

Is there an Outlook option that solves this or a message format where both
sections can be displayed at once?

What version of Outlook? Outlook 2002/2003 can certainly handle a message
of the format you describe. I though OL 2000 could handle it, too, but it's
bee a while since I used that version.

I have tested in Outlook 2007 and Outlook 2003 - neither display the message
correctly. I believe Outlook 2002 also suffers the problem. Outlook 2000 is
too old to matter :-)

The problem in that there are TWO inline sections. In the example I gave I
would expect the client to displayL

--start

plain text body

Footer

--end

However Outlook only displays one of these, the other is shown as an
attachment requiring the user to click on it to open it.

Other clients (every one I have tried) display both sections simultaneously.
