I am looking for a way to disable all user's Exchange property that allows them to use the HTTP protocol. In other words, I want to deny them access to use Outlook Web Access (OWA) by default unless I explicitly go in and give them access. I know where to change this setting on each user's profile in AD, but of course this would take me days to turn off for everyone.
I am in no way skilled in writing any kind of scripts. (although everyday I am seeing more and more of a need to learn)
We are a single domain environment, running Active Directory.
I would really appreciate help with this, as well as maybe pointing me to where the newbiest of newbies can go to get his feet wet in the world of scripting.
