OK, you look in the default ADM file for Outlook 2007 and you can’t find any option to configure the Outlook Anywhere settings? That’s probably because they are missing from the default ADM template.
But wait, don’t start thinking about customizing ADMs just yet, as there is one already customized that you can download.
Just take a look at the following article, it comes with a link to the page from where you can download the ADM as well.

Here are the policies you can configure using this new administrative template:
Also take a look at the “Explain” tab for the RPC/HTTP Connection Flags policy, it will give you more info on what connection options you can configure. Basically you can configure “flags” which correspond to options on the “Microsoft Exchange Proxy Settings” window.
For example, choosing the option “Flags 1+2” will enable the “Connect to Microsoft Exchange using HTTP” checkbox on the Connection tab and will also check the box for “Connect using SSL only” (see screenshot above).
