Hi Neil,

Did you get this working ?

As you've discovered, Exchange sucks mightily but your problem may 
actually be in IIS which is what Exchange uses for the web interface iirc.

As others have noted, the NTLM authentication scheme is turned on which 
will fail for any browser which doesn't support NTLM, which is everything 
apart from IE.

Even IE browsers will fail if the user *logged in* to the browsing PC is
not in the same NT Domain as the web server. In the case of the remote
user, this is almost *never* the case and NTLM will always fail. Useful 
huh ?!

It's discussed in this oldish MS article but the concepts haven't changed 
as far as I know.

Your best bet is to turn off NTLM and use Basic Authentication but then 
you *must* use SSL to avoid sending NT domain logon details across the 
wire in plain text. Which opens up another can of worms :)

HTH,

Simon.
