Exchange 2010: internal access to external OWA notworking.

Hello.
Last exchange issue I swear.Well at least for this client lol.

My remaining issue is that my internal users cannot access webmail from inside the network.
They can however browse to it by https://internalIP/owa
if they try to put in https://webmail.domainname.com/owa, it just times out.

Any ideas? is this a DNS record issue? If so, what DNS records to do I need to update.
My firewall is allowed all traffic from all trusted zones, external and optional zones, access to the NAT'd address for webmail. OUTSIDE access works absolutely perfect!

Thank you!

Hello,

What about HTTPS access to the OWA of Exchange 2010?

This states a way to get http access to webmail but HTTPS requires a certificate to be loaded and doesn't allow you to pick the URL.

Any thoughts?

I have the same problem with when trying to connect to the webmail address https://mail.mydomain.com/owa internally when using the same internet line as the exchange server. however i can access it by using https://internalIP/owa. (We have 2 internet gateways) If i switch internet gateways on my local PC to the line which the exchange server does not use, i can connect fine. Whats more unusual is after i have sucessfully connected to the webmail after switching internet lines, if i switch back to the previus gateway it now still works. However if i flush the DNS on my local PC it no longer works, which suggest its something relating to DNS.

Any thoughts anyone?
