You would REALLY want to upgrade Exchange to the most recent version. 
 A lot has been improved in 6 years.

Over 4 years, no? There is Exchange 2003 and Exchange 2007 is the 
latest. We wanted to upgrade too, but our management thinks otherwise 
:-)

Well, it is 2007 + Service packs that work with 2007....so, I will 
vote this is 6 years...


There are a LOT of holes in 2003, and the new version supports WebDAV, 
iCal, and other "friendly" features...

In this case Exchange is not in my side/responsibility :-(

What I found that Rebol could be used with Exchange by using IMAP 
protocol, but only with some authentication methods.
In my case it is NTLM and it it not supported by Rebol.

Would this help -- http://softinnov.org/rebol/ntlm.shtml

I have tested ntlm myself personally but not with Exchange but don't 
see why it woudn't work unless Kerberos was the method enforced.

Can I use rebol with gmail?

Has anyone here read messages off gmail?

I think Graham has been working a little bit with it, but I don't 
know the results.

These seem to work

open ssl://imap.gmail.com:465
open ssl://smtp.gmail.com:993

open tls://imap.gmail.com:465
open tls://smtp.gmail.com:993

But I can't get any further

I'm not sure how well the IMAP implementation works.

Nicolas, try this:
do http://www.rebol.cz/~cyphre/scripts/r2/toys/imap-cli.r


this is very simple CLI for access to google IMAP server (others 
should work too).


Once you run it you can just type at thh prompt IMAP commands. Snippet 
of example session:

Script: "IMAP CLI in REBOL" (none)
{* OK Gimap ready for requests from 90.183.64.72 27if531665fxm.20
}
IMAP>>login user pass

{* CAPABILITY IMAP4rev1 UNSELECT LITERAL+ IDLE NAMESPACE QUOTA ID 
XLIST CHILDREN X-GM-EXT-1 UIDPLUS COMPRESS=DEFLATE
A0001 OK [user-:-gmail-:-com] authenticated (Success)
}
IMAP>>examine inbox
{* FLAGS (\Answered \Flagged \Draft \Deleted \Seen)
* OK [PERMANENTFLAGS ()]
* OK [UIDVALIDITY 2]
* 5989 EXISTS
* 0 RECENT
* OK [UIDNEXT 70472]
A0002 OK [READ-ONLY] inbox selected. (Success)
}
IMAP>>

Hope this can be useful...

I posted scripts on rebol.wik.is for working smtp and pop for gmail

These both work well with Gmail (extensively tested):

http://www.rebol.it/power-mezz/mezz/imap.html

Unfortunately the documentation is not very good, but it shouldn't 
be too hard to figure out where it differs from the actual code. 
Also, if you grab the repository from Sourceforge, there are a couple 
bug fixes to mezz/imap.r
