Duplicate public folders multiplying out of control

You can globally prevent users from creating top-level public folders, which should prevent drag-and-drop duplication at the top level through the following procedure.

To remove the 'Create top-level public folder' permission:

1. Start Exchange System Manager (ESM).
2. Navigate to Folders, right-click the Public Folder node and click Properties.
3. Click the Security tab.
4. Under Name, click Everyone.
5. Under Permissions, scroll to 'Create top level public folder.'
6. In the Allow column, clear the checkbox.

To enable your administrative account to delete the duplicate folders, add your account to the top-level public folder hierarchy and assign yourself full control.

To set the permissions for groups and users to manage individual public folders, navigate to the desired folder through ESM, and click on either Client Permissions and/or Administrative Rights. Client Permissions allow you to select predefined roles that control permissions to create items, read items, create subfolders and establish folder owner, folder contact and folder visible. Groups need to be mail-enabled.

Administrative Rights sets who is an administrator for the folder. In most cases, these are settings don't need to be altered.
