Hi,
We can create a new appointment form and turn the option off programmatically.
Turning off the request responses programmatically consists of three steps.
- Create a custom form
- Publish the form in your Calendar folder
- Make the new form the default appointment form
To create a custom form, please follow:
1. In the Outlook Calendar view, click New Meeting to create a new empty meeting request.
2. Click Developer tab, click Design This Form.
3. In the Form group under Developer tab, click View Code.
4. In the Visual Basic Script Editor type the following:
Function Item_Open()
Item.ResponseRequested = False
End Function
5. On File menu, click Close.
To publish the form, click Publish drop-down list from the Form group and select Publish Form As. Give a name to the form and click Publish.
The last step is to make the new form the default appointment form. To do this, right-click the Calendar folder from the calendar list and select Properties. Click to select the form we created before from the "When posting to this folder"
list. Click OK.
Hope this helps.
Regards,
Steve Fan
