Hi @ser mar ,
You could follow the steps below to add the register key you would like:
(Note: Serious problems can occur if you modify the registry incorrectly. Before making changes, back up the registry to restore it in case something goes wrong.)
- Open Registry Editor.
- Navigate to the path you need, for example:
HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\outlook (If necessary, you can manually create the proper keys you need, for example like below:)
- On the Edit menu, point to New, and then click DWORD Value.
- Type ExcludeHttpsRootDomain, and then press Enter.
- On the Edit menu, click Modify, type 1 in the Value data box, and then click OK.
Hope this can be helpful : )
