Disable Outlook "Reply All" Functionality using Group Policy

1)     Download the appropriate Office Administrative Template files.

2)     Extract the Administrative Template files by running AdminTemplates.exe. Once extracted you should have 3 folders created (ADM, ADMIN, and ADMX):

3)     Create a new Group Policy that links users of the required organizational unit.

4)     Add the Office/Outlook Administrative Templates to newly created Group Policy


If performed successfully you should now see that the Microsoft Office Outlook 2007 Administrative Template files have been added in Group Policy Editor:

6)Once you have successfully added the Outlook Administrative Template, you need to properly define and enable the necessary policies. To successfully block "Reply All" functionality we need to enable and define two specific policies in the Administrative Template:

  • A policy to disable the actual command button as well as the menu option.
  • A policy to disable the keyboard shortcut.

To accomplish:

  • In Group Policy Editor navigate to the following path: User Configuration\Administrative Templates\Microsoft Office Outlook 2007\Disable Items in User Interface\Custom.
  • Once here you will notice 2 policies that will currently show as "Not Configured":
    • Disable Command Bar Buttons and Menu Items.
    • Disable ShortCut Keys.
  • To disable the Command Bar Reply-All button we need to select the Disable Command Bar Buttons and Menu Items Policy.
    • Once the policy is open set the State of the policy to Enabled then select the "Show..." button.
    • Any and all Outlook Command Bar Buttons that are currently disabled will be present here in a numerical context (although presumably this would be the first time working with the template so you would not see any numerical values present). Click Add, and in the "Enter the Item to Be Added" field, type 355. Once done click OK. You will be returned to the Show Contents page which should now resemble the following. Click OK:


    • Back on the Disable Command Bar Buttons and Menu Items policy page, select Apply and OK.
    • The "state" of the policy should now show as Enabled.
  • Now we need to disable the keyboard shortcut for Reply All. To do so, we need to open the Disable Shortcut Keys policy, configure our settings and enable it. To do so:
    • Select and open the"Disable Shortcut Keys" policy.
    • Select Enable, and then click the "Show..." button.
    • This will bring up the Show Contents page.
    • Select Add.
    • In the Add Item Window type the following: 82,12
    • Click OK which will shift the focus back to the Show Contents pane. Your value should look like this:

    • Back on the Disable Shortcut Keys property pages, select Apply and OK.
    • Back in Group Policy Editor, both policies should now show as Enabled:


They will also notice that the menu option for Reply-All is now disabled:


Bellow are some additional Command IDs and shortcuts
