Because public folders are considered a public resource, control over them is placed in the hands of a Microsoft Exchange Server administrator. Because an Event Service agent monitors a public folder and has the power to delete, route, or change documents posted there, the rights to create an agent are also controlled by an administrator.
The administrator must grant Owner permission to you so that you can author and run scripts in the monitored folder. If you created the folder yourself, your permissions are sufficient, and you can skip this procedure. If you are not the folder owner, a Microsoft Exchange Server administrator must perform these steps for you.

While installing Microsoft Exchange Server (version 5.5 or later), the administrator also installs the Microsoft Exchange Event Service. After the Event Service is installed, it runs automatically as a Microsoft Windows NTŪ service when you start Microsoft Exchange Server. During installation, a folder called EventConfig_<ServerName> is created in the information store. This folder holds information about the Event Service. Administrators determine who can install scripts to run on any particular server by granting them Author permission on the EventConfig_<ServerName> folder.
