Outlook: Adding and Removing the Folder Size Button

Can I add or remove Outlook's Folder Size button?

By default, Outlook places a Folder Size button on the General tab of the Properties dialog box for every folder within your mailbox. You can disable or reenable this button by editing the HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook registry subkey. Add a DWORD entry named ChkFldrSize. Set this entry's value to 0 to disable the Folder Size button or to 1 to enable it. For more information about this registry edit, see the Microsoft article "OL2002: How to Remove or Replace Folder Size Button in Folder Properties" (http://support.microsoft.com/?kbid=289571).
