Microsoft recommends that no more than 300,000 items are synced using OneDrive. That sounds like a lot, but it’s a limit easily reached if you’re syncing multiple locations and you have a lot of files going back perhaps years.
If you have a lot of data in your SharePoint site, you might consider only syncing the folders you actually need. See our guide on selective syncing of data from SharePoint below.
How To Sync
Syncing is easy. Make sure you are already signed into OneDrive before you begin using your company account.
Navigate to the library or folder that you want to sync. At the top of the screen you’ll see a number of action buttons. Click the one that says ‘Sync’
That’s it! You’ll see the SharePoint libraries listed in Explorer next to a new icon
