Were you on a domain computer with domain credential?

If you were using Internet Explorer along a domain account and has forward authentication enable (inside the browser setting), it is passing the domain credential across in the background so you don't see the prompt.

Try using BASIC authentication on the Proxy settings page. This will be safe because your using SSL in your example

Use DOMAIN\USERNAME or username@domain.local for your username and your regular domain password.
Make sure you change the DOMAIN to what it actually is for your infrastructure

Don't worry about the other security setting in the options before proxy, it can stay on NTLM

Hi there,
May be this would help me to identify problem:  My OWA is fine and clients work fine. via http://mail3.mydomain.com.

''the action cannot be completed.  The connection to Microsoft Exchange is unavailable.  Outlook must be online or connected to complete this action.''
This error pops up everytime I try to connect to my Exchagne 2010 RPC over https with outlook 2010

I am using external address https://mail3.mydomain.com
internal address of server exchage2010: https://exchange2010.mydomain.com
also: https://autodiscover.mydomain.com

All top three addresses are inclusive in my SSL certificate:


Outlook 2010: settings:
under connections tab:
connection settings: https://mail3.mydomain.com   (my external OWA address)
connect using SSL only checked
Only connect to proxy servers that have this principal name...........
msstd://exchange2010.fernhillschool.com  (my internal exchange server name, note that my ssl certificate has this name)
On slow networks, connect using http..............checked
NTLM auth under Proxy auth settings is selected



On my Exchange 2010:
Under EMC:
server config, CAS:

Under Client Access, right click over server name: outlook anywhere External host name: exchange2010.mydomain.com and NTLM auth is selected

Under outlook web app
Internal URL https://mail3.mydomain.com/owa
External URL https://mail3.mydomain.com/owa
under authentication tab, USE forms based auth, UPN selected

Under ecp:
internal URL: https://mail3.mydomain.com/ecp
External: https://mail3.mydomain.com/ecp
authentication=forms based authentication

Exchange active sync:
internal url: https://exchange2010.mydomain.com/Microsoft-Server-ActiveSync
External url: https://mail3.mydomain.com/Microsoft-Server-ActiveSync
authentication tab: Basic auth checked, ignore client cert

OAB:
inteternal URL: http://exchange2010.mydomain.com/OAB  <<<......note that this is http
External URL: https://mail3.mydomain.com/OAB


Under POP3 and IMAP4:
POP3: under authentication, x509 cert: mail3.mydomain.com

as I said previously in my comment

your exchange server is set for BASIC authentication

Exchange active sync:
internal url: https://exchange2010.mydomain.com/Microsoft-Server-ActiveSync
External url: https://mail3.mydomain.com/Microsoft-Server-ActiveSync
authentication tab: Basic auth checked, ignore client cert

so:-
in your HTTP Proxy settings, change NTLM authentication to BASIC.

then login using your correct username notation and password.

Yes. that is normal... OWA published by default with the ssl cert and normal access using http will show the warning to use https..
