I know, most of you (including me) using OneDrive or OneDrive for Business in your environment. But in some cases customers won’t allow users to save stuff on OneDrive or won’t let them connect to this service.
If you plan to disable OneDrive in Windows 10 1607 and Office365 Version 16 you have to consider two steps. Disabling it in the File Explorer of Windows 10 and the second point is preventing Office to offer for saving stuff to OneDrive.
All that can be done using a single group policy. Create a group policy and name it with your preferred naming convention. If you use the loop back mode you can use just one policy for computers and user settings.
First: Navigate to Computer Configuration\AdministrativeTemplates\Windows Componets\OneDrive\ and enable “Prevent the usage of OneDrive for file storage”. This will disable OneDrive in File Explorer and removes the cloud icon in the status bar of your Windows Clients.
Second: Navigate to Users Configuration\Preferences\Windows Settings\Registry and add a new Registry item. Create a new key with the following settings:
Key path: Software\Microsoft\Office\16.0\Common\Internet
Value Name: OnlineStorage
Value Type: Reg_DWORD
This key disables the option to save files on additional Online Storage such as OneDrive. Of course you won’t be abele to use SharePoint Online as well. Assign the policy to your computers and test it.
The result in the Office365 applications such as Word, Excel, PowerPoint, etc… is like that:
