Cheers for that, it worked a treat.

Now if I can only figure out why it repeatedly asks for authentication
I'll be sorted!  As an example, I'll go onto the /exchange/ site, and
it'll show the inbox fine.  It will then immediately pop up a
username/password box.  I enter the details.  I then click calendar, it
then asks me for username/password five times before letting me in. You
don't even have to be using and it'll pop up a username/password box.

Any ideas?

Joel.

Hi Joel, if you are using Exchange 2000 with OWA, unfortunately you need
to
change at the OWA web site, to use only "Basic Clear Text".   This will
increase the performance for outside users.  Since you have the SSL
working you won't have to worry about the lesser of the authentication.

IMPORTANT: To make the authentication change for OWA, you need to
perform it at the Exchange Server or the Front-End Server,by using the
Exchange System Manager Tool.

You should find the Authentication Button in the Exchange/Public

I have issues with the speed of it through ISA.  I find the initial
screen takes a very long time to come up (up to 2mins).  It's not a
bandwidth issue I'm sure, and it's perfectly quick from inside the
network.

My second problem is that it repeatedly asks for authentication, the
only way around it is to allow IE to store the username and password,
hardly secure!

Anyone got any ideas about the authentication?

Cheers,

Joel.

I should have mentioned that I used server publishing too... Glad it is 
up.  Mine is not too bad- the initial authentication takes a moment, but

the rest of it is pretty quick even over HTTPS.  I'm running it on a
pretty 
hefty box, though.

While we are at it, has anyone successfully published an off-site
Exchange 
Instant Messanger site for basic-authentication access to?  Any magic 
there?  I have not been able to get one to work...
