Q. How can I enable the Security tab at the Exchange organization level?

A. By default, the Security tab isn't displayed on an Exchange organization's properties page. To display the tab, perform these steps:

The Security tab will now be displayed on the Exchange organization's properties page. At the Security tabbed page you can turn off the Send As and Receive As deny settings, which I discuss in the FAQ "How can I configure Microsoft Exchange Server 2003 administrators so that they can access all users' mailboxes?" at http://www.winnetmag.com/articles/index.cfm?articleid=42867 to grant Exchange administrators full access to all mailboxes in the organization. The Security tab method is a simpler way to grant administrators access to users' mailboxes than the technique described in the FAQ; however, it lets you grant access only to all mailboxes (or none).
