How to Use OneDrive Sync Properly

OneDrive sync is one of those features that works brilliantly when set up correctly and causes endless frustration when it's not. The green ticks, blue clouds, and sync conflicts confuse everyone.

Here's how to set it up properly and avoid the common headaches.

Files On-Demand — turn it on

This is the most important setting. Files On-Demand means your files appear in File Explorer but don't take up disk space until you open them. A cloud icon means it's online only. A green tick means it's downloaded.

Click the OneDrive icon in your system tray → Settings → Sync and backup → Advanced settings → Files On-Demand → check 'Save space and download files as you use them'.

This stops your laptop's hard drive filling up with every file you've ever saved to OneDrive or synced from SharePoint.

Making files available offline

If you need to work on a file without internet (travelling, rural site, unreliable connection), right-click the file or folder in File Explorer and select 'Always keep on this device'.

The icon changes to a green circle with a white tick. This means it's downloaded and will stay downloaded, syncing changes when you're back online.

Don't make everything available offline. Pick the folders you actually need when you're disconnected.

Syncing SharePoint libraries

You can sync SharePoint document libraries to your local File Explorer too. Open the SharePoint library in your browser and click the Sync button.

The library appears under your organisation's name in File Explorer. Same rules apply — Files On-Demand keeps it manageable.

Don't sync every library. Only sync the ones you use regularly. You can always access the rest through the browser.

Fixing sync issues

The most common sync problems and fixes:

• Red X on a file — usually a naming issue. Check for special characters (# % &) or file paths that are too long.

• Sync is paused — click the OneDrive icon and resume. Sometimes it pauses because of metered connections or battery saver.

• Duplicate files with 'Copy' in the name — this happens when two people edit the same file offline. Open both, merge the changes, and delete the duplicate.

• OneDrive stuck on 'Processing changes' — right-click the OneDrive icon → Quit. Reopen it. If that doesn't work, reset: run %localappdata%\Microsoft\OneDrive\onedrive.exe /reset

For admins

You can enforce Files On-Demand and sync settings through Intune or Group Policy. This stops users accidentally downloading everything and filling up company laptops.

Known Folder Move is another setting worth enabling — it redirects the user's Desktop, Documents, and Pictures folders into OneDrive automatically. Go to OneDrive admin center → Sync → enable 'Silently move Windows known folders to OneDrive'.

If your team is struggling with OneDrive sync issues or you want to roll it out properly, we can configure it across your devices through Intune. No more 'my files aren't syncing' tickets.
