Signature in Attachment

In this case it happens to be the corporate version of Outlook with
Exchange server.  That's also why using other email clients really isn't
an option.  So as things stand for now, I may need to accept that I
won't be able to verify PGP/MIME signatures attached to the messages.
While it would be nice to be able to do this with Outlook, I can live
without it for now.

Thanks for the response and the great application that GnuPG is.

I doubt that the proprietary PGP handles PGP/MIME with Outlook.  There
is no documented or known way on how to send arbitrary MIME encoded
messages using Outlook (i.e. using MAPI). We have figured out a way to
decrypt/verify _most_ PGP/MIME messages but no way to create them.
Thus we have not started to implement something.

There are possible hacks of course but they would be really bad.  If
you are running a standalone Outlook you should try gpg-relay.
