This article is for Office 365 global or SharePoint admins who want their users to be able to sync IRM-protected SharePoint document libraries and OneDrive locations using the new OneDrive sync client.
Users are running Windows 7 or later. This feature is not yet supported on Mac.
You have IRM applied to a SharePoint Online library. (On-premises SharePoint Server libraries can't be synced with the new OneDrive sync client.)
Your users have disabled syncing using the previous OneDrive for Business sync client
This feature doesn't support the IRM setting that expires document access rights.
Disabling the previous OneDrive for Business sync client
To prevent reliability issues, any users that are using the previous OneDrive for Business sync client (Groove.exe) to sync an IRM-protected library must disable syncing.
On a computer that uses the previous OneDrive for Business sync client to sync IRM-protected libraries, right-click the blue OneDrive for Business icon in the notification area, at the far right of the taskbar:
Click Stop syncing a folder.
Select the IRM-protected library and click Stop syncing.
To enable this feature, you need to install the RMS client to your users' computers. Download the Rights Management Service client.
To silently install the client on computers, use the /qn switch as part of the command-line options of the Microsoft Windows Installer Tool (Msiexec.exe). For example, the following command shows the silent mode installation (assuming the RMS Client installer package is already downloaded to C:\Downloads)
msiexec /qn c:\downloads\setup.msi
You can have the setup file on a network share and use managed software deployment to run the msiexec command.
To sync an IRM-protected library
Have your users browse to the library in SharePoint and click the Sync button. This will open the OneDrive sync client and create the sync relationship for the location.
