Hi there !
I have a big problem.
I'm using Exchange 2010 on Windows Server 2008 R2...
On my settings the owa is configured on : https://mail.mydomain.com/owa for external acces.
When i go on IIS i see that the Default Website is running well and there is no redirections on it.
I Also have a DNS A Pointer to : mail.mydomain.com on my IP address.
And finally on my firewall i created a policy that allows traffic from any to LAN1 with service HTTPS.
But if i go on https//mail.mydomain.com/owa i get the 404 error....
I also tried an iisreset...
Someone can help me ?
