Redirect http to https on OWA IIS6.0 not working - chautran99

Hi,

I followed this note http://support.microsoft.com/kb/555053/en-us and
got everything working internally. when I type in http://servername in
automatically redirects me to https://servername/exchange which is
correct and what I wanted. The problem is that when i try this from an
external location i.e. when I type in http://domainname.co.uk or
http://domainname.co.uk/exchange it does not redirect me but when I
type in https://domainname.co.uk/exchange I can get to my exchange
server OK. MX record and external DBS is working fine as I get to my
exchange server from an external location without any problem. I can't
work out where exactly the problem. any help will be very much
appreciated. I am using exchange 2003 SP2 on windows 2003 server.

Thanks,

Chau
