If your site administrator allows it, you can sync any SharePoint document library to your desktop using the OneDrive sync client.
The sync client creates a real-time connection to your site. It is not a local copy. Any changes made, including deletions, are automatically sync'd between the server and your desktop.
If you don't see a Sync option, you either lack the permissions to do so or it's been disabled in the library. You can confirm this by contacting the site admins or the EASI IM Team.
To stop syncing, you must first unlink the library or folder. Do not delete a folder or a library from the sync client without unlinking or else you risk deleting all the content for everyone. For instructions on stopping the sync, see KB0010295.
