Outlook Programmatic Access and GPO on replace mode

We can´t enable the options for Programmatic Access on Outlook 2016.

Tried all the registry changes via GPO and opened Outlook as admin but the options still stay grayed out.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\x.0\Outlook\Security

 
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\outlook\security
DWORD: PromptOOMSend
Value: 2
DWORD: AdminSecurityMode
Value: 3
DWORD: promptoomaddressinformationaccess
Value: 2
DWORD: promptoomaddressbookaccess
Value: 2

I have seen that GPO is on "replace mode" and read that HKEY_CURRENT_USER  -settings are ignored on the "replace mode".
Is that true and how does it effect on this ?
Is the whole GPO created on wrong  way? I have never seen that before.
