Let users sync IRM-protected files with the OneDrive sync app
This article is for Microsoft 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 app (OneDrive.exe).
Any IRM-protected files will maintain their IRM protection during the sync process, both during upload and download. The OneDrive sync app doesn't support the IRM setting that expires document access rights.
You've applied Information Rights Management (IRM) to a library in Microsoft 365.
You've installed the RMS client on 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
Users sync IRM-protected libraries in the same way they sync other libraries. For info, see Sync SharePoint files with the new OneDrive sync app.
