Hello
I have just configured a New Exchange 2013 server.
On 2010/13 Outlook its fine, but on XP machines With Outlook 2007 its not working inside the domain.
It seems it not can authenticate againste the Exchange server inside address.
If I configure the Outlook manually I set the http Proxy adress to mail.domain.com and it Works, but if I restart Outlook the http Proxy setting is changed to the inside address exch.domain.local and it can not authenticate. The same problem With autodiscover.
If I use Outlook 2007 on the outside its no problem.
I tried to set InternalClientAuthenticationMethod to same as ExternalClientAuthenticationMethod, negotiate but its still not working.
What I want to find out is why its rewriting the http Proxy in outlook
