SharePoint sync issues when opening from File Explorer

Hi, This might Help. Please check the below steps:

1. Stop and remove the old sync

Click the OneDrive icon → Settings

Go to Sync & Backup

Stop sync for the affected SharePoint library

In File Explorer, delete the old SharePoint folder

2. Remove old shortcuts

Open File Explorer

Unpin anything under Quick Access that points to the old library

3. Re-sync the SharePoint library

Open the SharePoint site in your browser

Click the Sync button

Let OneDrive create a fresh folder

4. Enable AutoSave in Office apps

Open Word or Excel

Go to File → Options → Save

Turn on: “AutoSave files stored in the cloud”

Make sure “Save to computer by default” is turned off

5. Verify OneDrive settings

Click OneDrive icon → Settings

Make sure “Files On-Demand” is enabled

Make sure “Use Office to sync files (co-authoring)” is enabled

6. Open files from the correct synced folder

Open files only from:

“OneDrive – CompanyName” or

“CompanyName – SharePoint Library”

in File Explorer, not from old shortcuts or random locations
