The highest public folder in a hierarchy is called a top-level public folder. By default, all users in an Exchange organization can create top-level public folders. However, you can change this default setting with the Active Directory Service Interfaces (ADSI) editing tool, which is part of the Windows 2000/2003 support tools. Here's how:

  1. Start the ADSI Edit utility (Start -> Programs -> Windows 2000 support tools -> Tools -> ADSI Edit).

  2. Double click the Configuration container.

  3. Expand CN=Configuration, CN=Services, CN=Microsoft Exchange.

  4. Right click your organizational name's container and select Properties.

  5. Select the Security tab.

  6. Click Advanced.

  7. On the Permissions tab, find the entry with the name "Everyone" and a permission of "Create top-level public folder."

  8. Select the Deny checkbox.

  9. Click OK to exit all the dialog boxes.

  10. Close the ADSI Edit utility.
