We are setting up Exchange 2010 but want to limit down the users who can sync with ActiveSync with just an AD group. I have seen other solutions by using a powershell script but I would like to limit it down through IIS.
I have tried to set permissions on the security tab on the Microsoft-Server-ActiveSync site directory as read only and removed the authenticated users. We then tested and the user could get through without being in the group. So I changed the authentication from basic authentication to windows authentication and it fails for everyone.
Any help would be greatly appreciated! Thanks!
