Question about Outlook Express

Hello!

Outlook 2011 don't connecting to Exchange 2010 from external network, but from internal network all working.

For Windows 7 and Outlook 2010 our admins recommended import to registry follow keys:

[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\AutoDiscover]
"ExcludeHttpRedirect"=dword:00000001
"ExcludeHttpsAutodiscoverDomain"=dword:00000001
"ExcludeHttpsRootDomain"=dword:00000001
"ExcludeScpLookup"=dword:00000001
"ExcludeSrvLookup"=dword:00000001
"ExcludeSrvRecord"=dword:00000001

After I am importing this keys Outlook 2010 is working from external network. Before Outlook 2010 always asking credentials and in settings for proxy authentication automatic changing to "NTLM Authentication" instead "Basic Authentication".

I am finding similar recommendation for Outlook 2011:

"To disable autodiscover in your Outlook for Mac clients you can run the following AppleScript:

tell application "Microsoft Outlook"
set background autodiscover of exchange account 1 to false
end tell"

After this Outlook 2011 working fine in internal network, but from external network nothing change. Always ask credentials and after I am input it right don't working.

Please help me solve this problem.
