In the previous issue of Exchange Messaging Outlook, I explained how to use group policy to disable the tentative response option. The July 3 2018 Outlook 2016 update builds in the ability to remove the Do not Send a Response option.
The required update is in Outlook 2016 Click to run and is now available in the volume licensing version when the July 3 2018 Outlook 2016 update is installed.
To hide the Do not Send a Response option, add the DWORD ForceMtgResponse to the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\Calendar DWORD: ForceMtgResponse Value: 1
You'll need to restart Outlook after setting this key.
Administrators can add the key using Group Policy.
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Options\Calendar DWORD: ForceMtgResponse Value: 1
Do it for me
If you don't want to edit the registry yourself, you can download and run a rready-to-use registry fil e to set the key.

Outlook 2013
In Outlook 2013, the only option is to disable the menu option, adding the CommandID to the key at
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\x.0\Outlook\DisabledCmdBarItemsListThe CommandID for Do Not Send a Response is 19987. Instructions are at Use Group Policy to disable commands Use Group Policy to disable commands Use Group Policy to disable commands
is there a way to go back and have the option do not send response?
You need to remove the policy or registry key to have the option back.
19987 only greys out the option within the email side of the response. If you right-click on the meeting in your calendar, or use the banner menu from your calendar, the option is still available. Do you have those other command IDs?
This is the list of appointment control ids for the appointment forms - the controls should work for all instances of the control.
