Adobe Acrobat DC FeatureLockdown does not work (Outlook Plugin and Sharepoint)

I have to deploy Adobe Acrobat DC in our enterprise and facing an issue with the feature lockdown.

I set the registry keys HKLM\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown

- \cCloud --> bAdobeSendPluginToggle DWORD 0

- \cSharePoint --> bDisableSharePointFeatures DWORD 1

But I still have the "Add Account" option to add a SharePoint account as well as the "My Account" icon in Outlook and the "Send & Track" option.

Disabling Sharepoint works for Adobe Reader DC, but not for Adobe Acrobat DC.

Is there another possibility to disable those features, for example using the customization wizard?

The registry keys were added by an AutoIT script after the setup finished.

Thanks in advance.
