Explanation:
You need to configure a Group Policy Object (GPO) with the OneDrive settings required to redirect the Documents folder of each user to Microsoft 365.
Importing the OneDrive group policy template files into Group Policy adds OneDrive related settings that you can configure in your Group Policy.
One of the group policy settings enables you to redirect ג€Known Folders ג€ to OneDrive for business. Known folders are Desktop, Documents, Pictures,
Screenshots, and Camera Roll.
There are two primary advantages of moving or redirecting Windows known folders to OneDrive for the users in your domain:
✑ Your users can continue using the folders they're familiar with. They don't have to change their daily work habits to save files to OneDrive.
✑ Saving files to OneDrive backs up your users' data in the cloud and gives them access to their files from any device.
