If you disable this setting, the Office tab is hidden in the sync client, and coauthoring and in-app sharing for Office files is disabled.The Users can choose how to handle Office files in conflict setting will act as disabled and in case of file conflicts, both copies will be kept. It typically takes one to two weeks to completely roll out to this ring.Notes: This policy enables users to collaborate on documents in real time and share them from the Office 2016 and Office 2103 desktop apps.Enabling this policy sets the following registry key value to 1: [HKCU\SOFTWARE\Microsoft\One Drive] "Enable All Ocsi Clients"=dword:00000001 If you enable this setting, it displays the Office tab in One Drive sync settings, and selects "Use Office 2016 to sync Office files that I open" by default.Enabling this policy sets the following registry key value to 1.[HKCU\SOFTWARE\Microsoft\One Drive] "Disable Personal Sync"=dword:00000001 If you enable this setting, users will be prevented from setting up a sync relationship for their personal One Drive account.
Also, the first letter of the ADMX file should start with a capital letter, but now I am nitpicking.
For info about using the One Drive admin center to control sync settings in your organization, see One Drive admin center.
To administer One Drive with Group Policy, install One Drive and copy the One and One files from %localappdata%\Microsoft\One Drive\Build Number\adm\ to your Group Policy central store.
To get the ADMX files, download and extract the ZIP file containing the installation sources. But since I am a bit of a stickler, I still see room for improvement.
The ADMX and ADML files are located in the subdirectory policies. For example, the name of the ADMX file should always start with “Citrix” in my opinion.
