Didn't get any replies here, but I found the solution.. If any of you are interested, the Attribute Name in AD that controls the 'Mobile' settings in AD is named 'MsExchOmaAdminWirelessEnable'. After finding this, a quick google lead me to this KB Article that describes how to set all user settings (including new user accounts) to disable the Mobile features. http://support.microsoft.com/?kbid=830188 Keep in mind, the article sets the default value of 0 to 7 to disable all mobile permissions. I am setting the value to 5 so that OMA still works but user inititiated sync and UptoDate Notifications are disabled by default. Hope this helps those of you out there that are also worried about mobile security on your network!

Okay all - I want to control who can and can not establish ActiveSync connections with Exchange 2003. In AD, when creating new user accounts, the 'User Initiated Synchronization' is set to 'Enabled'. I would like to have this set to 'DISABLED' instead for all current and newly created accounts. I know that I can disable this feature after creating the account through 'Exchange Tasks', but I want it to default to Disabled. Without having to use Group Policy or relying on Admins to copy a template user account, is there a way to modify AD to default the 'User Initiated Synchronization' and 'Up-To-Date Notifications' to DISABLED? FYI - This is so I can have granular control over what users are able to use the ActiveSync features of Exchange 2003. Thanks for ANY help on this! Chris
