I use Outlook Desktop 2019 on Windows 10. For me, Ctrl+D is hazardous because it deletes an item when I actually meant to type (say) Ctrl+S or Alt+D. Furthermore, the mapping of Ctrl+D to deletion is completely unnecessary because there is already a Delete key.
I a following this process to disable Ctrl+D. It says to navigate to HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\version\Outlook\DisabledShortcutKeysCheckBoxes. Unfortunately, I can only get as far as Computer\HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft. There is no "Office" subfolder.
I also tried the this process for editing the Group Policy. It says to navigate to User Configuration\Administrative Templates\Microsoft Outlook 20XX\Disable items in user interface\Custom. Unfortunately, I can only get as far as User Configuration\Administrative Templates. There is no Microsoft Outlook 20XX subfolder. I did launch gpedit
as administrator.
Why would the required paths not appear in "regedit" nor "gpedit"?
This Office installation is legit.
