You can disable any menu or toolbar command, such as Reply to All, by using a Group Policy Object. The article at http://office.microsoft.com/en-us/as...402401033.aspx explains how; look at the section on "Disabling menu items and command bar buttons."

If you don't want to write your own code to recurse the Explorer.CommandBars
and Inspector.CommandBars collections to get the IDs that you need to be able to disable certain toolbar and menu commands, you can use the Outlook Spy tool from http://www.dimastr.com. I also have a complete list in the appendices to my "Configuring Outlook 2003" book (see signature).

In the folders list on the navigation pane, there is an option to click on
data file management. I would like to remove it so that our users do not
accidentally delete old backup .psts and so on...

How can I do that?
