Re: OWA Premium

I just want to thank you and Lanwench for the information you gave me!
It was most helpful! I personally don't feel comfortable using
Exchange 2003's encryption when emailing confidential information
outside our company; it just seems like there are a few too many "if
and and but" factors and problems that crop up are not easily resolved.
People outside our company are seldom computer people, so we've now
moved on to look at simpler alternatives.

Have a great day and thanks again!

Hi! I have a few questions that I hope people can help me with:

Where can I find pricing information on OWA premium?

Users of OWA Premium: Are you happy with the encryption and digital
signatures in OWA? What are common problems you've faced?

If an encrypted email is sent from OWA Premium or Outlook 2003 (running
against an Exchange 2003 server), what will an external user see and have
to
do to view that email (and attachment). What mail clients (outside of
Outlook) can handle these encrypted messages--Outlook Express, Netscape,
Eudora, Mac Mail, Web-based clients (like accessing the messages through
hotmail, etc.)--so they are unencrypted and viewable to the user?

Thank you for your assistance!

Hi!
OWA E2k3 has a great S/MIME implementation, best suited for internal
corporate use.
When there is a corporate CA OWA behaves just as described in
http://www.microsoft.com/technet/prodtechnol/exchange/2003/library/exmessec.mspx .
Some features of OWA suggest that it was designed precisely with the
internal corporate
use in mind. When exchanging secure e-mail with external correspondents,
some problems
may show up.
Cryptigo has been testing OWA in such environment and some test results and
reflections
have been published in a blog at http://cct-blog.cryptigo.com/
None of the major mail clients supporting S/MIME (OE, Thunderbird, Outlook,
TheBat, Eudora)
have any problems with communicating securely with OWA. Even the
OWA-generated document
format is accepted, contrary to warnings in the OWA documentation.
Web-mail clients do not generally handle encrypted messages, they only
display smime.p7m
attachment that has to be viewed with an external viewer, such as p7mViewer.
For some
webmail clients, dedicated plugins are available in test versions
