Environment: Exchange 2007 RTM Outlook 2007 RTM Server 2003 SP1 A/D I'm trying to finda way to administratively alter the default permissions level for user's calendars in our Exchange environment. By default, Outlook/Exchange sets the permissions level for a new account as "Free/Busy time". I would like to grant "Free/Busy time , subject, location" as the permissions level for the Default. I managed to find the PFDAVAdmin tool, but it does not appearthat this tool incorporates the free/busy permissions levels that exist in Exchange/Outlook 2007 - there are no options for "Free/Busy time" in regards to calendar permissions. Are there options in the PFDAVAdmin tool that I'm missing or am I looking in the wrong place? Any help is greatly appreciated. Thanks! Trevor

Did you ever find an answer to this? I'm having the same issue, for legal reasons I need to changes these settings on all users accounts and would like to know if there is a way to do this at the server level, regestry settings or maybe through GPOs so I don't have to address it from the Outlook client level.

Sure did. Check out this tool:http://gsexdev.blogspot.com/2008/03/default-calendar-permission-powershell.htmlYou need to have a knowlegde of PowerShell and Active Directory/Exchange permissions, but once I got the tool working, I was able to change the default permission level for user's calendars using the GUI.Trevor
