Disabling 'Reply All' in Outlook

This was being discussed on a private list today and I didn't realise you could use the the Office Admin templates for this very function.

We all appreciate their use in disabling automatic archiving and the use off PSTs so I thought I would echo the post located here, as I see this as another nice 'value add'.

1. Download the admin templates from

2. Extract the templates into a directory

3. Modify the outlk12.adm file with the following changes

Goto line 2459 (KEYNAME Software\Policies\Microsoft\Office\12.0\Outlook\Security
Move the line VALUENAME PromoteErrorsAsWarnings below this line (it should located under VALUEOFF NUMERIC 0 which causes an error when Group Policy reads the file)
Find the line CATEGORY !!L_Disableitemsinuserinterface
Add the following lines immediately after that line (this will add the ability to disable the Reply to All button)
POLICY "Disable command bar buttons and menu items" KEYNAME Software\Policies\Microsoft\Office\12.0\Outlook\DisabledCmdBarItemsList PART "Enter a command bar ID to disable" LISTBOX VALUEPREFIX TCID END PART END POLICY

4. Create a GPO

5. Add the outlk12.adm template

6. Browse to Microsoft Office Outlook 2007\Disable items in user interface

7. Open the Properties for Disable command bar buttons and menu items. Enable this object
Click the Show button and Add 355

UPDATE: Microsoft have a good article on it also. Read it here:
