Ok, so I inherited the exchange environment, no biggie, but I need to create a new public folder on the root, however, I dont have rights. 2007 SP1 has a new command I can use.
Add-PublicFolderAdministrativePermission -Identity "\Marketing" -User "Chris" -AccessRights AllExtendedRights -Inheritance SelfAndChildren
However, my only question was (and I know i'm a noob) how do I add myself to ALL public folders, I just had to change the identity to "\"
Also to list your Identity's, use this command
