Re: S/MIME Attachments in Outlook 2002 (2003)

[Vizvary Istvan III]

Contrarily to this behavior, Outlook Express (I am using version 6)
displays

the s/mime-part by showing an attached file named "smime.p7m" (or
"smime.p7s" alternatively if the attachment is signed only).

Both applications in Windows versions support S/MIME, so I suppose
that you use Outlook Express for Mac.
There are S/MIME plugins available for Mac Outlook versions.

No, I am working under Windows XP - thus my Outlook Express is the Windows
version. I know that Outlook basically supports s/mime, but obviously not in
context with attachments.

Therefore, these questions remain:
-How can I get access to the s/mime-part in Outlook 2002?
-At least displaying the attachment as "smime.p7m"-file would be helpful?

TIA,

There is at least one situation in which these two applications display
s/mime parts as attachments when they are properly configured regarding
security.
This is could be when an agent modified the mail so that it is no longer
a valid S/MIME message and becomes and e-mail with a p7s or p7m attachment,
or
simply a corrupted S/MIME message.
Such an agent could be, for example, a non SMIME compliant SMTP server.

We use Outlook Express 6 and Outlook 2000 but could not force them to
display
valid S/MIME messages in the way you described. Maybe we should have tried
a little bit longer

-At least displaying the attachment as "smime.p7m"-file would be helpful?

If the message is corrupted indeed, but has an smime attachment,
you could use an external viewer (such as my own
http://www.ppuvas.com.pl/p7mviewer )
to decode the p7m part and access the content.
If the message is untouched, you should rather try to get your
Outlook configured properly.
