If you want to hide or block the toolbar in MS Word for non-DCP users on a terminalserver, please check the following steps:
1. You will have to create the following Reg key under current user instead of local machine:
(for example: HKCU\software\Microsoft\Office\Word\Addins\Wordmailmerge.connect)
3. Once you have created the reg key you can change the load behaviour for each user. Change it to 2 to block the toolbar for the user.
That’s it! We appreciate your feedback! Please share your thoughts by sending an email to firstname.lastname@example.org.
