Using something like Outlook Express is very dangerous, since it
means that you can be exploited if an email message arrives in your
inbox and is displayed. If you do use something like Outlook
Express, be sure to configure it to disable scripting and make it
as restrictive as possible. Unfortunately, in the case of Outlook
Express, this doesn't appear to be enough since I can't find any
setting that will stop things like IFRAMEs from automatically
loading, which are enough to make you vulnerable in many situations.
Hopefully I'm missing something.<<<
I wrote Microsoft a few days ago asking about shutting off HTML in =
Outlook Express, and here's what they wrote back:

Eric,
I am afraid that inbound functionality for turning off html code is not
possible in Internet Explorer as default.=20
There is no pure "html" to "text" converter or selection within the
application. It is unfortunate, I know, and I am sorry to have to =
deliver
this message to you.
I have however, passed your issue along to members of our development =
staff
for that feature to be included in future revisions. The very question =
you
ask is being considered at the most critical levels of our development
process.=20
The current conventional logic behind why we do not have a html to text
converter is the overhead that would be placed on the machine, browser =
and
email app that would seriously hinder performance.
I appreciate the your time and patience while I have researched your
question. I will be archiving this issue as unresolved. If you have any
questions, please contact me.
Thank you in advance,
harryb
