Outlook 2010 forced to use Outlook Anywhere on LAN against Exch. 2010

[AbstracCure]

I am puzzled by this: The Outlook 2010 has a checkbox "Connect to Microsoft Exchange using HTTP" checked. If I uncheck it and restart Outlook, it is checked again. It is happening on the LAN and I can't make the Outlook to connect to Exchange. Remote users can use the OA to retrieve their emails. Local user can't. How do I make the Outlook to not use the OA on LAN ? We have a SBS 2011 server.

The olkdisc.log shows that autodiscover.xml was found. There is a line in this XML which is probably wrong, or maybe not. See here:

<Protocol>
<Type>WEB</Type>
<Internal>
here --->> <OWAUrl AuthenticationMethod="Basic, Fba">

https://remote.someurl.com/owa/</OWAUrl>

<Protocol>
<Type>EXCH</Type>
<ASUrl>

https://remote.someurl.com/EWS/Exchange.asmx</ASUrl>

</Protocol>
</Internal>

<External>
<OWAUrl AuthenticationMethod="Fba">

https://remote.someurl.com/owa/</OWAUrl>

<Protocol>
<Type>EXPR</Type>
<ASUrl>

https://remote.someurl.com/EWS/Exchange.asmx</ASUrl>

</Protocol>
</External>
</Protocol>

Why would it want me to use basic forms based authentication on a LAN ? I think that might be the problem, yet got no idea how to fix it.

Thank you for meaningful ideas.

That's your OWA config, which should use FBA.

Does remote.someurl.com resolve to an internal address?
