XADM: Security Tab Not Available on All Objects in System Manager

In Exchange System Manager, the Security tab is displayed in an object's properties. However by default, the Security tab is displayed only on the following objects:

• Address Lists
• Global Address Lists
• Databases (Mailbox stores and Public Folder stores)
• Top Level Public Folder Hierarchy

To display the Security tab on all objects, you must add the following registry key.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

1. Start Registry Editor (Regedt32.exe).
2. Locate the following key in the registry:
   HKEY_CURRENT_USER\Software\Microsoft\Exchange\ExAdmin
3. On the Edit menu, click Add Value, and then add the following registry value:
   Value Name: ShowSecurityPage
   Data Type: REG_DWORD
   Value: 1
4. Quit Registry Editor.

This change takes effect immediately; you do not need to restart Exchange System Manager. This change only affects the currently logged on user. If the ShowSecurityPage value is not present or is set to 0, the Security tab is available only on the objects listed in the "Summary" section.
